Once upon a time Aymeric Poulain Maubant shaped the electrons to say...

Yes, it has always been that way.

If it recognizes USEMAP that takes precedence, if not it ignores it and
uses ISMAP.

Because you WANT to allow both - client side maps reduce server load
and speed user interaction - but not all browsers support them.  So the
older ones will call your server, but the newer ones get the benefit.
