I don't think it's necessary.  SET and SET SESSION are semantically the same so
nothing should rely on how exactly someone spelled it.  This is also the case
for our core jumbling code, where we guarantee (or at least try to) that two
semantically identical statements will get the same queryid, and therefore
don't distinguish eg. LIKE vs ~~.
