because this is how it worked.
i'm not saying it was good. it worked that way, and introducing such
change made some code (rownum in this example) not working.
i understand that postgresql is more about correctness than end-user
niceness, which has some obvious benefits, but i think - in such cases
at least a one-line information in release docs wouldn't be out of
place.

i think it's great idea. somebody thought about cool thing for modules,
other people found other uses for it.
right now they are being effectively punished for
creativeness (unfortunatelly i can't say it is me, as i got the variable
trick from somebody else).
