I think that's also a valid view of the problem (i.e. the further away from pure Python you get, the more complex and unclear things are). But I also think that's just the view from the "library developers" perspective — if you aren't publishing a library, but using Python for some other purpose, you are going to run into issues even at points that, from your perspective, are already fairly solved. For example, for application developers, even if they just stick to pure Python dependencies, there's still no standard lockfile format that standard Python tools can just emit and ingest. At best, you've got `pip freeze`, but you'll need to use custom tooling to update and maintain that, or switch to pip-compile or another, more full-featured package manager. To me, lockfiles really are table stakes here, but they're not at all easy to get working in Python.
