Yeah, this is my perception as well. My lukewarm take is that because so much of the stuff packaged was written in C/C++ for so long, the packaging systems are mostly optimized to work well with the quirks of thing written in them, but that sometimes comes at the expense of stuff written in other languages. In a lot of ways, distro package managers basically have evolved the role of pip/npm/Cargo/etc. for C/C++ packages, which leads to a mismatch when trying to also use them for other languages in pretty similar ways you might expect when trying to grapple with handling a build with an arbitrary pair of languages from the list above
