Why do you say that when the standard page doesn't mention it?
(http://pubs.opengroup.org/onlinepubs/009695399/utilities/find.html)

In fact, it gives examples using "." as the starting position, so it 
doesn't make
any logical sense that dir/. would be blocked.

It sure looks like POSIX does NOT require it.  "-delete" is a gnu 
extension,
so it wouldn't be covered either.

There is no mention of prohibiting patterns with a "." with the "remove" 
function.

The only place they broke that was in "rm"...

So I ask where you get the idea that it is required by POSIX.
