You're asking for something that's not possible. AMSAT can officially
use one thing in publications (and has I've stated, generally adheres
to that - with possible exception of the monikers for the less well
known C/X band combination), but getting an entire community of
amateurs to use consistent terminology is not likely to happen.
For example, AMSAT-OSCAR 85 is no longer Fox-1A. It was renamed upon
successful launch and activation per a longstanding satellite (and not
just amateur satellite) tradition. Yet I still hear lots of people
still call it Fox-1A or even Fox-1.
One thing that does irritate me is hearing linear transponders
referred to as "analog transponders" or "the analog birds." Many FM
transponders are analog in nature and, regardless of the
implementation, are still relaying analog signals. And, of course,
ARISSat-1 carried a linear transponder that was digital!
