Yuan would be the best to answer that.

Personally, I envisioned a custom highlight helper function like
rust-ts-mode--fontify-pattern or rust-ts-mode--fontify-scope which
seems like the simplest solution that should cover this use case, but
I'm not actually aware of all the sorts of craziness one could get up
to in a macro invocation so that might not be enough and maybe injections
are the way to go.
