[Tagging] Time to deprecate place=region and boundary=region?

[egil]

I began looking at this after finding a boundary=region in Ladakh, India 
that caused this region admin_level=5 not to show up in nominatim or on 
the main map.

Of the tags mentioned below only place=region has a wiki-page where it 
is not marked as deprecated.

I much prefer boundary=administrative + border_type=region over 
boundary=region and place=region.

What do you think?


Stats:

https://taginfo.openstreetmap.org/search?q=region#values

7 362 border_type=region
3 209 place=region

And

338 boundary=region
