Deprecation in the general sense ? What does that mean ? Is seems for example that the deprecation of a software feature SHOULD NOT imply a deprecation in Wikidata. Only an end date, as it has been true that the software had this feature. Deprecation on Wikidata is for stuffs that have never been true, just were thought true.
It seem to me that that something that was thought true but is not anymore is deprecated in the general sense does not add any information. What are your usecases ?
First of all, follow BRD. You were reverted and you started a thread, so far so good. In the mean time, status quo rules, and it's wrong of you to put your change back again.
Now. No one is suggesting deprecation of software implies deprecation on Wikidata. But deprecation on WD is NOT just for things that were NEVER true, it's also for things that USED TO be true and no longer are. That's why other reasons for deprecation include replacement (Q23009439), demotion (Q464858), resignation (Q796919).
Finding examples of misuse, like your rail station, obviously does not imply that an item is always misused. There are plenty of legitimate ways to use deprecation (Q280943) as a Wikidata reason for deprecation (Q27949697). Take one example: dog's bollocks (Q18612566) part of (P361) British English (Q7979) / reason for deprecation (P2241) deprecation (Q280943). The construction was part of British English, but isn't any longer, so the Wikidata statement is deprecated. Why? Because the construction is deprecated. The reason for deprecation (on Wikidata) is deprecation (in the real world). Swpb (talk) 13:07, 19 August 2019 (UTC)
See Help:Ranking#Deprecated_rank that contradicts your claim. Also see the Wikibase data model : https://www.mediawiki.org/wiki/Wikibase/DataModel#Ranks_of_Statements that states the same thing. Deprecated rank is NOT for stuffs that used to be true but are no more.
