Reproducible builds would be nice here, sure, but outside of a few weird exceptions in dynamic builds we already have what the author wants here. I agree with this point, but maybe using the cryptographic hashes from a VCS is better than a checksum? Other than that, I don't think there's any reason to tie the two together. > This would be great but... the author is an engineer right. How much have they thought about this? This would be a gargantuan undertaking. An awesome feature no doubt, but the maintenance effort... Actually, not really a gargantuan undertaking. Large, yes, but that's only to tell the VCS about the semantics of each language. The actual algorithms to do so are pretty small, and the semantics needed for each language consists of a lexer and some dumb knowledge about the structure, i.e., what a function looks like, what a type definition looks like, etc. Source: I am designing those algorithms right now. Other than that, I agree with your points, except that I'm now making a competitor to fossil. :) [1]: https://news.ycombinator.com/item?id=31792303 https://news.ycombinator.com/item?id=31792303
