I guess I would argue that the vast majority of users who get one of these
Logitech keyboards simply want a keyboard; they don't really care that
they got a general-purpose Bluetooth adapter in the deal. So breaking
that by default doesn't necessarily seem like the right idea. That said...

...it sounds like it's maybe been broken in this way for a while? My
machine has been riding the Rawhide train for years, it's possible it
doesn't correspond to what I'd get if I just dumped F15 onto it.

Perhaps the first thing to do is to try to figure out if it's only me.
Nobody else has griped on the Rawhide front, but, then, I think I may be
about the only Rawhide user left (and people keep telling me that I
shouldn't be there either). If it's only me I'll figure out how to put
the keyboard into a mode where it's agreeable to pairing, grumble for a
moment, and get on with my life.
If others are affected, it would be nice to detect the situation and put
up a little warning, preferably on the login screen. Not sure how easy
that would be to do.
Thanks for the explanation,
