I mean, I've never understood "open source" to require reproducibility? That concept barely even existed as a thing people strove for until 15 years ago, a lot of software still only barely supports such, and there are tons of tradeoffs that come with it (as you effectively then also inherit your entire toolchain as vendor maintained, and a lot of projects end up making that result in awkward binaries, as almost no one reproduces entirely from a small bit of bootstrapped lisp).
