This is a good question. I have a few thoughts. First, different languages have subtleties that can make a different in package management. For example, the way nested dependencies can work in JavaScript, Go, and PHP are all different. Or, the way you can scan a codebase to determine things is difference. It would be great if different languages had virtually the same interface. That way metadata and interaction could be about the same. Like diving a car from different manufacturers. In many ways the different package managers are similar enough for programming languages were sorta there (but not all that well). Second, there is the cultural problem. Many languages are designed on islands from others. Reinventing things, trying different things, and wanting to be their own special flower. Sometimes this is good because a new language is not like the others and that can be a good thing. Other times you reinvent a fairly common wheel. I'm not aware of anyone solving this in a common way.
