How many is "a lot", and do any of the responsible vendors sit on the SQL
standards committee?

One large concern about doing anything like this is whether future
versions of the SQL standard might blindside us with some
not-terribly-compatible interpretation of that syntax.  If we do something
that is also in Oracle or DB2 or one of the other big boys, then we can
probably rely on the assumption that they'll block anything really
incompatible from becoming standardized ;-).

OTOH, if the actual meaning of "a lot" is "MySQL", I'd be pretty worried
about this scenario.
