Yes, I'm afraid existing scripts will do something like:

$address = gethostbyname($hostname);
if ($address == $hostname) {
        echo "Error....";
        ...
}
        ok...

I think perhaps the reason for current behavior is that gethostbyname()
on some systems may not return the IP address when called with an IP
address, the current PHP code would hide that bug. Well, just a theory
I don't like the current code either.
