My suggestion was that it should *become* invalid/get a warning in - let's say - HTML5 docs.

But an author which -today- inserts %FC is likely to do a mistake - or at least make a bad choice, no?

How common are such servers these days? 

My focus is authors. And of course it could be the author meant %FC. But might it not more often be simply a result of a bad %-encoder or on a misconception?
