And I would prefer it to be DISALLOWED rather than PVALID, if we are 
going to eliminate the rules.

It's not just about appearance.

"Yes Dad, as long as you are on double-you double-you double-you dot 
paypal dot com, you are in the right place."

"Hmm. I've got three double-yous, a dot, and then paypal then another 
dot, and then com. That seems to be what he was saying. I must be OK."

Dot and slash-like characters are uniquely problematic, and dot even 
more than slash, because top-level domains have dots but no slashes.
