nufmt isn't ready to be released.

[nikolay]

@fdncred That's why there is alpha, beta, RC, and other types of pre-releases.

[AucaCoyan]

Yes, but nufmt isn''t even in a alpha state, it currently corrupts code.
You can take this repo more like a "field experiment" than a releasable app in whatever name convention you can think of

There's nothing wrong with having a PR ready to go, maybe we can just keep it in draft mode
