OSM doesn't really have deprecated tags, except in special cases (for 
example highway=ford on a way is a bad idea, because you can't say what 
kind of ford it is).

Also "castle:type=manor" hasn't exactly troubled the scorers so far, has 
it?   https://taginfo.openstreetmap.org/tags/castle:type=manor shows a 
grand total of _3_.

I wouldn't read too much into the wiki here.  I suspect that almost 
no-one who tags these objects has read it (and I'm basing that on a 
fairly extensive analysis of the usage of historic tags in the UK and 
Ireland).

Speaking as a data consumer, not really.  Some aspects of historic 
tagging were difficult, but those were the questions of "is that thing 
still there", "is that thing a building/ruined building, or the grounds 
in which the building is" and "this has a historic tag and lots of other 
tags; which to render"?

For info the relevant bit of the list that I'm using for "historic stuff 
to render" starts at 
https://github.com/SomeoneElseOSM/SomeoneElse-style/blob/master/style.lua#L1571 
= that's only a long list because I'm looking at all historic stuff, not 
just "castle" and "manor".

I'm using exactly the same rendering pipeline as OSM's standard style, BTW.
