technically all of those are "unused" because they are mere
documentation.  but that documentation is still nice to have :)

well, Noel is currently working on converting these to the less-unused
new-style services...

that isn't sufficient: it's possible that it's only used from Java or
Python code, or worse, only used from an extension that is outside the
LO repo (though probably the latter case is rare, and indeed begs the
question what it's doing in offapi then...).

my opinion is that while there are probably a few more useless relics
like ProductRegistration, IDL removal requires a case-by-case review anyway.
