That's simple enough and easy to test.

At the moment they are.  They lack ascii support, but at least keywords
should be supported in ascii eventually IMO (but that's another thread).

So I would keep them.  The documentation explicitly states which backend
these keywords are supported by.

This category would not exists in the code.  It would simply be a
classification that exists in the manual.  I would be a hack to not
maintain "no. of backend that support SOME_KEYWORD" different places to
maintain documentation for SOME_KEYWORD.

Anyway, the above is fine so let's use that.
