Bootstrapping the compiler isn't a sign of language maturity. V has changed pretty significantly both in terms of syntax as well as semantics since that release.

Regarding compile times, why do you claim less than one second when your own tracking shows 2.5 seconds and trending upwards? (fast.vlang.io) Aren't you concerned that as the compiler and language are actually implemented, compile times will continue to worsen? Have you considered that perhaps that's why there are so few languages that claim that kind of bootstrap time?
