This is definitely the case in DL (and I'm assuming elsewhere too but I wouldn't know).

I've lost count honestly, running 1-2 year old paper github repos with some detail missing (like the Python version!) that make it non-trivial to run as is. Libraries make undocumented breaking changes, wrong pickle format, authors used a nightly version which didn't make it to a tagged version, and so on.

This perhaps says also something about the CS (versus software eng) background that most people engaging in DL publishing have.
