No, we use thumb-elf tools locally. Stuff works fine, to the best of
my knowledge.

Yes, it may not build for people using more recent tools. But the
support is there. It's just a question of using the correct runes to
get it going.  Those runes are what I referred to in the PID
CDL. Clone that, but replace thumb-elf- with appropriate -m<options>
and you should be set.
