Well, the paper
https://eprint.iacr.org/2013/339.pdf
does not use the term perfect, which I think is a good idea.

Better to stop perpetuating a marketing word!  Besides, forward secrecy has not alternative meaning to worry about.

FWIW, I once presented to a bunch of quantum computing researchers, and blithely used the term "perfect" to which they strenuously, and logically, objected.

Best regards,

Dan
