Isn’t that like saying “glad Typescript exists but still prefer Flow?” One does a tiny subset of the other after all, and when you compare what Flow does to what Typescript does, I think it’s possible to argue quite well that the very tiny subset of what Typescript does is arguably comparable to what flow offers but that perhaps you might get basically everything that Flow offers and 100x more if you adopted typescript. And perhaps Flow might be better at several things but if it’s only really good at solving 5% of the total problem I’m going to pick the solution that also solves the other 95% even if the 5% Flow solves is just a mediocre solution

Note that I don’t really think that bun is the solution for everything or really that it is all that great. I am just pointing out that you are trying to compare two things that are not really the same thing at all. One is probably a strict superset of the other
