Agreed - because I think SFP brings with it a whole host of issues that
describing the media facing port would be error prone - and to do it
accurately, we'd need a table of quirks to fix lots of broken modules.

For example, many SFP modules with RJ45 connectors describe themselves
as having a LC connector!
