I'm not sure.  Adoption seems to be picking up:

But note that interoperability with Mac (and iOS, where you explicitly
have to turn HEIF off if you don't want it) is pretty important even to
GNU/Linux users.

But I also don't see it as a major problem (just a small one) if we give
it a year or three to see if this format really starts to really pick up.
