Well thats just rude. Undoing someone's work because they're not using the data source you want them to.

Just realigning the data to its tagged source. Feel free to tag your changes as "personal guess based on a single aerial photo" and allow others (including me) to decide which is the more reliable source. Of course you are free to survey the area yourself over a period of months and account for tidal variations due to atmospheric pressure, seiche waves and other phenomena...

Regarding "undoing someone's work..." that is exactly what you are doing...

As nice as it would be to have a single reliable and up-to-date source of truth for coastline data. the OS maps arent it.
https://wiki.openstreetmap.org/wiki/Ordnance_Survey_OpenData
The wiki page already states:
"1. Don't assume the OS data is either correct or up to date. Use it as a guide and additional resource for your mapping, not a replacement."In addition to that and like I said before. The MHWL data contains plenty of errors and are years out of date in some places.
To show a select few examples:

https://cdn.discordapp.com/attachments/718028525021429832/1163364621286113340/image.pngAll of these are very clearly in error and show that the OS data isn't foolproof and should not be relied on as the sole source of coastline data.
