Using CC-BY-NC-SA would mean, if we ever invoked the SA
clause to bring any external changes back into the OEIS, that
it could never be put to any commercial uses, even if the
OEIS Foundation wished to approve such uses.  One important
commercial use is the publication of the next book version,
and there are doubtless others (like the ones explicitly allowed
by the current license).  That is the rationale behind proposing
CC-BY-SA instead of CC-BY-NC-SA.
