Is PDF encryption, modern or not, actually widely used

IME, no. I suspect that this is largely because it suffers from the requirement to share the password with those others you wish to be able to read the document. And if you are going to share the password securely, why not just share the document securely? When I do have a need to share a PDF securely with someone I just encrypt it with their PGP public key.
