Obviously I'm not adverse to using the occasional, non-IANA code point. But
they need to be picked randomly and outside the dense, IANA area.
Otherwise, this is certain to happen in short order.

I think quite a lot of clients are going to be advertising compression
using this code point in the coming months. They should only do so when
offering TLS 1.3, which presumably LTS clients would not, so maybe there's
something you could use there.
