In any case this will break backwards compatibility in a way it did not
happen in PCBnew, EEschema always looks for symbols in libraries (including
the cache) when loading a file (there are no embedded symbols to fall back
to), so suddenly making certain names not resolve will cause schematics to
break upon opening. To avoid breaking previous designs either a special
case needs to be done for the cache (my least favourite option), or like
Chris says, let each plugin define what's legal or not.
