This is definitely a thing though.
On this very topic, many llama.cpp PRs are good examples. A model trainer may present a PR with poor understanding of the (very complicated, highly specialized, sparsely documented) project. Then a maintainer comes to fix it, but has absolutely no knowledge of certain things the model trainer would know (“Oh, the whole thing NaNs if this one value on layer 23 isn’t FP32!”)
There has to be a back-and-forth. A whole lot of it.
That is an exception, yeah.
But I’m not sure I’d call it “rare.” There are definitely situations where fixing without explaining is ultimately a whole lot of work.
