EventTriggerSupportsObject() (currently named
EventTriggerSupportsObjectClass()) is only used by the deletion code,
and these additional classes are not supported there anyway. Also, if
they happen to show up there for some reason, then
EventTriggerSQLDropAddObject() would error out in
getObjectIdentityParts() or getObjectTypeDescription(). So you wouldn't
get an event trigger firing on a previously unsupported class by
accident. So I think this is robust enough.
