The problem with hashes of hashes is now instead of the password being directly grabbed, the hash is directly grabbed, which can be thrown through the challenge-response system with no problem.

This only mitigates knowing the password itself, not anything to do with authentication.

But now you have to grab the hash first from one of the endpoints, MITMing the connection no longer suffices to impersonate the user.

I suppose public key schemes would be preferable, but deploying those isn't feasible for a lot of use cases.
