Pefectly acceptable? Perfectly? Really? I have 10 year old C and Go projects that build and run fine as if nothing has changed. I can upgrade the dependencies if I want to but that's on me. The projects themselves have no problem building and running fine.

Just to try it out, I took one of my old C projects written in 2010, last code update in 2012. It's a machine learning utility to train maximum entropy rankers. I was a bit worried because it used CMake (rather than a vanilla Makefile). It configured and built without any issues (and super-fast).

Lol, Go was notorious for breaking with its "pull from main"/lack of lockfile approach.
