[PATCH] D75574: RFC: Implement objc_direct_protocol attribute to remove protocol metadata

[Nathan Lanza via Phabricator via cfe-commits]

lanza added a comment.

> Hmm, I thought we actually just generated a bogus definition for the protocol when it was forward-declared; really, this is better behavior that I expected. Regardless, I don't think it's worthwhile to diagnose this more strongly than a warning because of the history of not doing so.

That's fair!

> Not really important for this PR anyway. Was your question answered well enough to move forward?

Yea sure, I'm okay with leaving it as a warning and moving forward and fixing your suggestions. I just wanted to make sure to cover any possible concerns.
