I didn't say mandatory.  I said "would be nice".

In this case the lack of documentation feels related to the cause of the
bug -- no authoritative place to say what the proper name is.  I don't
see it as "another random chore".

The names don't match.  That's a bug.  I was wondering whether the right
thing was to remove SYS in one place or add it in the other (or have we
given up on maintaining the distinction?).  I didn't expect asking that
question to be a huge burden on the patch's progress.  It was also
bundled up in a patchset with a bunch of non-bugfixes, so it didn't seem
like you were asking for urgent handling of this one.

And look at what I get for doing so. :-)

While I would have liked an answer to the questions I asked, it's not
worth arguing over, so:
