The problem under discussion is that projects that currently use CPython have slow startup. One potential solution is for those projects not to use CPython. (Certainly it's not the only potential solution, but, a language that tries to be all things to all people isn't going to succeed. Python has so far done an extraordinarily good job of being most things to all people, with "I want native-code performance" being one of the few out-of-scope things.)
