So this recipe is something that stopped working recently?  Can you
tell when, or bisect?

I'm just tired of investigating recipes that eventually lead nowhere.
The way Emacs approves and rejects fonts doesn't guarantee that a
request to use a given family will always be granted.  Moreover,
fontconfig setup on the user's platform is also relevant.

It isn't.

The default font would be my guess.  Try using some other font, not
from the fixed-misc family.
