Yes. Most of the problems I have with global parameter still apply to this

If we absolutely have to do this with a separate piece of information, I would
opt for a content-feature tag. That way there's a clear delineation between
when feature information is or is not present, and we don't mess up MIME
parameter space. And we need the feature tag anyway for negotiation purposes.

I still strongly prefer the suffix, however.
