Hi! It's very important to not create too many elements and harmonise the different elements together. For this you should check OSM's Wiki on how to create more simple elements, for example:
- these 2 ways (footway https://www.openstreetmap.org/way/586960646 & cycleway https://www.openstreetmap.org/way/586960650 ) can be created within one single way (with these tags: highway=path + foot=designated +bicycle=designated + segregated=yes)
- you created these dedicated sidewalks which are not connected to any other way https://www.openstreetmap.org/way/586981883 https://www.openstreetmap.org/way/586982744 https://www.openstreetmap.org/way/586982744 etc... which makes them totally unusable for routing. Also in my opinion, dedicated sidewalks should only be created when the sidewalk is quite different from the main road, unless special case like the segregated dual way footway+cycleway which obviously are not directly attached to the road, seperated by parkings. Otherwise if it's directly aside the road, better add the tag sidewalk=both or left or right or no. It's way is more simple.
- Also avoid nodes on straight lines, this creates extra data for nothing and makes it hard for portable devices to handle OSM maps.
I know it's quite to consider but it's for the greater good of the map and saves you time for future edits. Thanks for your comprehension :) -

I personally think that sidewalks should be mapped as separate ways. I looked into the wiki on sidewalks and there doesn't seem to be a consensus on that.
I think it has advantages, especially for those who travel by foot, to have dedicated sidewalks mapped as their own path. For example crossings are better visible with that method.
For the rest, thank you for your advice!

There are consequences you may not realize when the map gets a certain level of complexity / many elements per "screen" :
- specially on mobile devices like dedicated GPS devices which use also vectorized OSM data, the mobile device is very much slowed down due to its limited processor not being able to handle the amount of data.
- also on the rendered image maps, the amount of detail gets over crowded. I find that we have to zoom in closer to make things clear, making us have a narrower map at the same time, even on a desktop computer i found myself zooming in/out several times when i created routes. In bigger cities it is OK and kind of obligatory because the sidewalks are much bigger and we need to connect specific ways like those going to tunnels in Royal Hamilius. In Lux city, you only see sidewalks on boulevards or avenues. Somehow, this issue is like the parking spots along roads you had created, they are rendered on the map, overloading it with "P" icons whereas someone is more interested in searching for a parking area. It would be OK if the area is rendered in a different color like in the past, but now on Mapnik it's also a shade of grey.
- the straightforward directions in terms of viewing the routing can get broken or lets's say zigzagged because some routing engines do not care about the type of way, they just take the shortest direction, which makes the routing jump from roads to sidewalks and vice versa. On bicycles or even running, if you look quickly on the GPS, the user may think he has to turn whereas he just has to go straight.I don't know if you have much experience with these kind of mobile devices for a certain activity but these are the issues i have found when the maps gets
If you really have a good reason for creating so many independent sidewalk ways, then you have to make sure that any of it is interconnected to allow a routing choice. You had created so many isolated ways (islands) or contours not connected in a network fashion which forces the routing to go around certain directions instead of taking the shortest direction.

* I don't know if you have much experience with these kind of mobile devices for a certain activity but these are the issues i have found when the maps gets overly detailed and complex.

Forgot that if you create mostly dedicated sidewalks, you have also to integrate the hiking routes otherwise this will introduce conflicts.
