Per-language package management seems to be the way to go lately. I think this is mostly because some operating systems don't have a package manager, or have one that is difficult to create and distribute packages for.
If I make a package using $LANGUAGE's package manager I get portability across the platforms that $LANGUAGE supports, and I do it I using tools that I already know and am already using to write in $LANGUAGE. Market share == $LANGUAGE's market share.
But If I want to make an $OS package for my $LANGUAGE module, I have to use a tool unrelated to my language and package that I probably don't know and target only $OS (or do that step for every one of them). Not to mention that the specific ones that we have, say RPM and DEB, have always been a right pain for me to generate personally. Market share == $LANGUAGE's market share / $OS's market share.
I don't like the state of affairs, but I do understand why people end up distributing with their language's package manager instead. It's way simpler and already baked into their process and assuming that they wrote the code in the first place to scratch their own itch and they already know how to use their language's package manager, it solves that problem for them nicely.
I think one solution is for language-specific package managers to target creating OS packages on some common platforms (`setup.py make-deb`, `cargo deb`, etc). These modules are probably so similar that it's much easier than the package case.
If an OS has no software management subsystem, it is not enterprise deployment material, and therefore has no business being used to power production; it really is that simple.
There certainly are uses outside of enterprise, but then it's not enterprise, is it?
If however such software is used for generating money, then suddenly, the exact same criteria as within enterprise applies, because as soon as the flow of money is jeopardized, that's production.
I'm not sure what point you're trying to make here. I'm saying that my original comment had nothing to do with enterprise. It may well be that operating systems without package management are unsuitable for enterprise. I personally think operating system without package management are unsuitable anywhere; my comment, however, was descriptive rather than prescriptive.
