Does this block a general swap of the defaults from 14 to 16, or is it
just a blocker for Mesa moving to 16 as a result of something Mesa-specific?

Is there / does there need to be a transition tracking bug for this?

Perhaps to avoid the trip through NEW it would be pragmatic to make
rust-bindgen be temporarily or permanently a multiple-upstream-tarball
binary package that combines the upstream projects bindgen and
bindgen-cli, avoiding needing to wait for NEW on the critical path?
