Huh. I suppose it is.
I think it would suffice to treat the number of supporters as one less
if the initiator is non-first-class. This could cover With N Support
as well, replacing "or N+1 supporters".
What if the initiator is first-class but the performer isn't, or vice
versa? *looks again* Wait a minute, you don't disqualify either the
initiator or the performer from supporting! Anyway, that will need to
be worked out as well.
