I think having pluggable language features would be nice; on the one hand, you’d keep the “1 obvious way only” people happy- just don’t use it, or come to some agreement with your team - and on the other hand you’d be able to scratch itches for people whose main value for Python is plugging into its ecosystem rather than the language itself. Heck, why limit it to 4 dialects, you could have a whole Babel scenario where you could pip dialect install some nice language feature. I think people would mainly be using this type of feature to reduce mental burdens, for a small buy-in
