Personally this (and key exposure) would be very useful. I am trying to implement committing AEADs such as the CTX construction. Since it replaces the tag, a non-authenticating decryption would allow me to drop in any AEAD trait such as CtxCommitment<XChaCha20Poly1305, Blake2b512>.

If the existence of the traits is okay, I can also give a shot at adapting the hazardous traits for the implemented AEADs.
