As an example, look at how NIST define "permission" in one of the early RBAC papers: https://nvlpubs.nist.gov/nistpubs/Legacy/IR/nistir6192.pdf

Here "permission" is defined as an "Operation/Object pair" - for example, read/write/execute access to a particular file. But crucially, there's no user involved (yet). That's where authorization comes in. When a permission becomes associated with a user (in this case via roles), you have authorization.

This sense of the word "permission" has now become very well established in the field of identity and access control.

Great info. I think you’ve established that authN and authZ are perfectly adequate but I think the fact you had to dig this up shows they aren't widely understood.

The proposed renaming seems like it would solidify the lack of understanding, which would be an undesirable outcome.
