In my experience, the hiccups with packages are of a different kind than those with LaTeX packages. They’re more often “normal programming” hiccups where a function is poorly-documented, or there’s simply a bug. LaTeX packages can cause bigger problems: even usepackage-ing them can do arbitrary ‘stuff’ and have weird nonlocal effects that are basically undebuggable. Oftentimes two packages will just be incompatible, which should not ever be the case in a sensible programming language.
