Yes.

Exactly.

I can see reasons why some users would consider it not just reasonable
but "The Right Thing" in their specific situation.  The argument would
be as simple as "Which part of `bold` don't you understand?" and would
fundamentally be just the same as the argument that we should not use
a monospace font when the "sans-serif" family is specified.

I'm not sure either, but I think the current discussion around
`variable-pitch` is similarly influenced by the fact that that we
specified the `:family` (and on top of that the face is called
"variable-pitch"), so it's obvious (to us human) that the desired result
should not be a monospace font.

IOW the context of this discussion implies a bias towards putting more
precedence on `:family` but we could restart this discussion replacing
"variable-pitch" with "bold" and "family" with "weight" and most of the
arguments would hold just as well, just favoring `:weight` this time
around :-(

In any case, I do support inclusion of your patch on the `emacs-29`
branch as "the best solution so far".
