As others have pointed out system package management is quite different and solves an overlapping but distinctly different set of problems to programming language module package management. In particular system package management isn't cross platform whereas programming language module package management tries to be. The programming language module package management has to integrate with whatever system package management is doing.

However, I do think you have a valid point in that there are plenty of commonalities between the software module package management needs of different languages. There is little need for each language to re-invent its own system.

It certainly would be considerably more challenging to develop a system that could work for multiple languages, and then there are the existing ecosystems to consider in terms of (the huge) cost of migration, mindshare, etc.

But in principle, you are right, even if economics means that it cannot happen in practice. No need for Yet Another One. But it will happen because economics.
