If you are lucky, it does not reject any valid emails.

For sure, however, it is not the 3-page 'correct' validation and
therefore must accept at least SOME invalid emails...

Almost for sure, it doesn't accept the new-fangled international emails.

Presumably, if a built-in PHP function did this, changing it in one
place would make everybody's code work right for this monumental
change...
