How about a naming convention instead, where using a leading
underscore in a parameter name is a hint that it is positional-only.
For example, the docstring of sorted:
 sorted(iterable, key=None, reverse=False) --> new sorted list
would become:
 sorted(_iterable, key=None, reverse=False) --> new sorted list
In any case, boy am I -1 on this. If you wish to continue this proposal 
further please write your own PEP.
A leading underscore indicates a private implementation detail. The proposed signature now looks like we can provide a key and reverse, but only riskily provide the actual thing we want sorted. No warm fuzzy feelings there! ;)
