Pkl is newly open sourced, but it not new. It's been used for years at Apple, and has been battle tested internally.

I'd actually say that our tooling in some ways is more mature. For example, I think our IDE experience (at least in JetBrains editors) is the best out there.

There is no trust in the words “we tested this internally.”

Apple employees can rate it as an old project among themselves, while it is more convenient for everyone else to rate the product from the moment of publication.
