Same as hashnode.com/ama/with-babel-team-cj7awmk5e00ij54w…. Which ones aren't supported? https://github.com/babel/proposals pretty sure we cover most if not all, it's definetely not a few haha?

We follow the TC39 proposal process, mainly. Anything that's been accepted as a stage-0 proposal by TC39 (and was presented to the committee or has a clear understanding of the semantics). We've tried to outline this at babel/proposals

There are a few primary factors that come to mind:

Proposals that are not syntax-related are usually left up to core-js to polyfill, and some new features just can't be polyfilled
We're a volunteer team, so someone needs to come forward with the interest to implement a given proposal, and ideally keep it updated.
Some stage 0 proposals are expected to iterate quickly, which it less likely that someone will want to maintain it.
