Just ignore me. I need more coffee.

The universal behaviour is correct: a compiler-macro lambda-list is a
/macro/ lambda list, after all.

Interestingly enough, that also means that there is no ways to use
&KEY to specify non-keyword keyword arguments in a compiler-macro
lambda-list that doesn't run roughshod across the evaluation model.
