or at least the problem is more apparent for italic as the differences 
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 
than relying on heuristics
for example while answering a question I wanted to use rsfs (or 
euler) for script in addition or instead of
the script in stix because well just because that's what the question 
asked for, and it seemed  that the easiest way
currently is to use|\||mathup{\euler{A B C| to disable the mathcode 
mapping which works but looks a bit odd.
