...no. Many of them are used in contexts where markup is not
really appropriate, like modifier letters. And many superscript
letters are newly encoded in Unicode for that reason.

For math, you're right. But I would still not say that using
super- or subscript digits in cases like H₂O, m², ¹⁴C, or 10²³
is even remotely wrong and should use markup instead. That
would be quite unnecessary overkill, when font coverage of
these characters is quite sufficient (and survives markup
stripping, though not compatibility mapping; hoping that
my examples will survive e-mail).
