I agree! However in many cases, these edge cases (I'm not speaking of curl now) are not needed for my personal use. E.g. if I use linux/windows/os, I do not care about how my tool behaves on the other os, I do not want to support all kind of hardware etc. If I am the only users, I can prune these use-cases (and features I mentioned in the post) significantly. E.g. I reimplement a subset of vim at the moment, I do not use LSPs or syntax highlighting in my work, I do not need to implement support for them in my editor.
