I regularly can't do that in LaTeX due to changes in packages. Yeah, the core is stable, but dependencies are still an issue in TeX land.

That's only true if you need a lot of speciality packages. For the vast majority of people using LaTeX, they only need the core packages like the basic features of hyperref, geometry, amsmath, amsthm, and in that case, they are quite stable.

I've never had a problem recompiling documents. Yeah, you might have a problem if you're using LaTeX for a fringe use but most people don't.
