... although that's a really contrived example.
I'm not sure it's TRT to add too much complexity there, so I would suggest
to add an additional optional argument to face-differs-from-default-p, to
exclude one or more attributes from the comparison (in this case :extend,
but someone else might be interested in excluding other attributes in the
future).
