Warn for water=salt

[naoliv]

We have 6628 objects with water=salt ​https://overpass-turbo.eu/s/v6G
It isn't documented at ​https://wiki.openstreetmap.org/wiki/Key:water and most probably it should be salt=* ​https://wiki.openstreetmap.org/wiki/Key:salt and/or landuse=salt_pond ​https://wiki.openstreetmap.org/wiki/Tag:landuse%3Dsalt_pond

Could JOSM warn about water=salt, please? (it should also include a suggestAlternative for both salt and landuse=salt_pond)

salt_pool is actually ​https://wiki.openstreetmap.org/wiki/Proposed_features/Salt_pannes_and_pools
So shouldn't be warned

Replying to naoliv:

salt_pool is actually ​https://wiki.openstreetmap.org/wiki/Proposed_features/Salt_pannes_and_pools
So shouldn't be warned

I set it to abandoned for several ​reasons.
