The above works fine on my system: I get a "fixed" font without the
"--eval" argument, and variable-pitch font with it, as expected.
It sounds like so do you, but you don't like the variable-pitch font
you get, is that so? If so, then the problem is with the fonts you
have installed, not necessarily with what Emacs produces. That is,
assuming you do get variable-pitch font in the buffer, why are you
saying that Emacs doesn't perform correctly? The font being "ugly" is
something only you know.
I'm guessing that what you see is due to some attributes of the
"fixed" font used as the default face's font. The commit you
identified as the culprit preserves the attributes of the original
font which the face doesn't override, instead of throwing them away.
So I think the pretty sans-serif font you wanted to see is rejected
because it doesn't fit some of those attributes of the default face's
font. Can you try figuring out which attribute(s) are those? It
could be the :weight attribute, for example (the "medium" vs "regular"
issue, which is new in Emacs 29), or maybe :size.

Please tell the details: which faces are broken and how?
P.S. And why isn't this reported as a bug to the bug-tracker, instead
of here?
