On the contrary: if the generation of such variants by the font backend
is inhibited, Emacs will display bold text with overstriking, when these
variants are absent from the font itself.

I should clarify that "generation" refers to the automatic generation of
oblique or bold fonts undertaken by a handful of our font backends, not
the overstriking implemented in xfaces.c.

No, see above.  However, the matter at hand is that I can't understand
the deficiency OPs request is supposed to address.  Surely, if the
author of a package which inserts icons wishes that they not be bold,
the package should set the face by which they are displayed to one that
isn't?

Thanks.
