I still think this needs to be commented on by Nick as it involves a
significant change to the HAL definition, and he's both the HAL in general and
specifically Cortex-M HAL architect. So I'm assigning this to him and see if he
grumbles :-). He can always assign it away if he's not interested in commenting
on the API change.

But I wouldn't overstate the problem, as far I can tell this will only happen
with certain designs of devices, and only then if certain situations combine,
which therefore makes it uncommon. That's not to say it's irrelevant, but it's
not like it happens every interrupt or anything like that.
