Did I? 

My point - and I'll stick with it until I'm taught better:

Improvements (often) do not justify breaking existing rules.

Or in this particular case: Adding members-exclude to as-set without
defining it somewhere "officially" (syntax and semantic) BEFORE, seems
to me NOT the right way. (Esp., as the target is to get this into the
complete IRR "eco system" and not just into RIPE.)
