One use case is that if a user specifies a locale, say, of 'de-AT',

Canonicalization should not lose useful information, it should just
rearrange it, so I don't see a risk here based on what I read and the
behavior I saw. In ICU, "de-AT" canonicalizes to "de_AT" and becomes
the language tag "de-AT".
It turns out that 'de_AT' is actually a distinct collation from 'de' in
CLDR, so that was not the best example. What behavior do you see for
'de_CH'?
