All that Guido is proposing to do is to rationalize development effort
on something people are already doing by standardizing a good-enough
approach, on an opt-in basis. Sure, there are people who want
something more coercive, but Python developers aren't going to stand
for that, and Guido himself is the first line of defense. He's
already said that's not going to happen, not now (and IIUC probably
never).
