You could do that for the built-in tags, but you can register custom tags  
too, and verifying those would be difficult.

In <https://github.com/toscho/t5-rewrite> I provide a placeholder  
%_custom_%(fieldname)", eg. "/%_custom_%(gender)". I will solve the  
problem you described in one of the following versions with a live preview.

Has to wait until I’m ready to convert the current, rather noisy template  
list into a <datalist>.

It has the advantage to provide feedback immediately, and I don’t risk  
side effects as a result of overly greedy validation. When a user wants to  
break the permalinks – be it so. :)
