What are the chances of someone wanting to disable this feature only
for some fonts?  If we want to allow disabling it globally, it should
be a simple matter of adding a boolean variable exposed to Lisp, and
then performing this only when the variable doesn't inhibit that.

Adding a font property, or a regexp for matching fonts which are
exempt from this, are by contrast much more complex and require more
changes.  For a feature that was so far requested by a single user,
I'm not sure this is justified.

As for your example: if Doom uses this for icons, why cannot Doom
refrain from using bold face for these cases?
