The metaclass system already allows for fairly significant variations
in "class" semantics. In this case, a metaclass that disallowed
instantiation and bypassed the normal class lookup machinery seems
entirely feasible.

That doesn't seem any more fundamentally confusing than using the same
syntax for normal classes, metaclasses, ABCs, enumerations, database
ORM models, web framework form and view definitions, etc.

Cheers,
Nick.
