or at least the problem is more apparent for italic as the differences=20
between
math and text setting are more glaring in that case:-)

Yes, although I think what's needed is an explicit way to do this rather=20
than relying on heuristics
for example while answering a tex.sx question I wanted to use rsfs (or=20
euler) for script in addition or instead of
the script in stix because well just because that's what the question=20
asked for, and it seemed  that the easiest way
currently is to use|\||mathup{\euler{A B C| to disable the mathcode=20
mapping which works but looks a bit odd.
