It's for when the default face uses a variable-pitch font, as I
believe I already explained.

And instead of repeating the same arguments again and again, I think
we should simply agree to disagree, and wait for others to offer their
opinions and experiences about this.

I don't think I understood what you consider a bug here.  Face
attributes are calculated when the face is created, they are not
updated whenever the default face changes.
