Comment (by bsalisbury1):

 I believe the Stembridge axioms are valid for any crystal with a simply-
 laced Cartan matrix, with no assumption that the crystal is finite.  Can
 the Stembridge axioms be moved to the regular crystals category with an
 added condition that if the cardinality of the crystal is infinite (or
 unknown), then only test to finite depth?
