To be more future-proof, similarly to EncryptWithLabel, I guess we could design a similar function for the HPKE AuthPSK mode?
This would help ensuring future extensions that would be using the AuthPSK mode with leaf HPKE keys don't interfere with each other.

@raphaelrobert will take care of this once we decide what to do with targeted message extension.

It looks like this point has been addressed with the safe extensions API. However, Targeted Messages re-define a safe API for SealAuthPSK, this could be moved in the safe extension API.
