Well - there is no formal deprecation of tags in OSM, to deprecate a tag 
in a meaningful way you need to have consensus to not use the tag any 

Before you can however suggest an alternative tagging for a certain tag 
you need to document this tag - i can't for example tell you if i think 
route=horse is a sensible alternative to route=riding if i don't know 
what route=riding means.

Looking at your three cases:

* the first is not actually in use (probably someone deleted or changed 
the three cases taginfo lists already).
* the other two are apparently used very inconsistently but mostly for 
subjective 'structuring of geographic space' concepts likely mostly 
imported from external sources.  None of this looks verifiable and 
therefore does not belong in OSM and should be deleted.  Many of these 
are also relations with other relations as members which is a big no-no 
in OSM.

In other words:  These are all issues that should be addressed working 
on the data.  Re-tagging these into something different would just bury 
the problems between other data.
