That was me being VERY generous to the other proposal :) At very best,
what you're seeing is an *upper bound* on the number of people
referenced, but I wasn't actually arguing numbers there so much as
disputing the incredulity given.

HOWEVER: Your proposal is much easier to make backward compatible.
Adding a keyword-only parameter to a method that currently doesn't
accept keyword arguments is (a) not going to conflict with current
code, and (b) will instantly error out if someone attempts to use this
feature on a Python that doesn't support it, so it's not going to
cause subtle errors.

Though, notably, this would count as another use-case for PEP 463, if
anyone felt like reviving that.
