Maybe, ofcourse, this exact same construct is used heavily in DELETEs.
Look at the syntax of the delete command:
DELETE FROM [ ONLY ] table [ WHERE condition ]
You can't declare extra tables or define aliases. Every other table
used in the query is by strict definitions "undefined". Should they all
be declared illegal too?
Perhaps you could argue that using undeclared tables is allowed for
DELETEs but not for SELECTs. But why make a distiction if you don't
need to.
Hope this helps,
