This statement of a lack of community is at odds with the plentiful pull requests that were open before the rewrite.
This is, as you say, unprecedented. Not impossible, cautious optimism is a fine response. But to bring back a point I made earlier in the new old light: Then let's be cautious. Let's do some announcements ahead of time. Let's get some people in and get some physical hands on the codebase. Let's not go from "Stop freaking out, it's just an experiment!" to a silent merge to main in a week. That causes reduced trust in the project from those even just a hair less optimistic than you, and that's clearly unhealthy for the project no matter how you define "the community."
If an experiment goes wildly successful beyond imagination, rapid pivot is only natural.
Jarred earned the trust by providing value. People who say trust is reduced without actually seeing the result, never had trust to begin with.
It's not like they merged and dumped it on to the world immediately. It's available as canary. They are doing their own dog fooding. Prisma is using the canary successfully.
As long as oven team can deliver a zig version equivalent stable bun, it is a success in my book. After that they can focus on resolving as many unsafe as possible and then the real benefits will materialize.
