Please read what I wrote. Problems which made distributions necessary no longer longer exist yet their approach makes other problems that do exist unfixable in the distribution paradigm.
Obviously. Because work done by distributions implicitly assume that others, too, have these exact same problems and spend a lot of efforts trying to solve them.
What distributions are doing is based on the assumption that it's okay to “freeze the world” (to then ship frozen and tried and tested form on tapes, floppies or CDs) and that others would have to deal with these issues, too.
But today it's entirely impossible to do that: different projects have different schedules and, more importantly, developers don't want to spend insane amount of time trying to support long-obsolete libraries (crates) from that “frozen world” release time. Like MMO games expect that you would update their client hours after update is available developers of rust crates expect that they would be able to pick the bugfix hours after it's released on crates.io
and rip out the temporary workarounds (if these workarounds were even written in the first place).
This makes pretty much all modern software (not just Rust crates, but also PyPI packages and Node.JS packages) fundamentally incompatible with what distributions expect.
In an era where you were lucky if you had a friend with a modem and could download patches from BIX or CompuServe, where the ability to get updates was a privilege which very few can enjoy, where you had to to deal with years old bugs and had to ensure that obsolete versions of dependencies can still be used… in that world what distributions needed to exist was natural consequence of how development already naturally worked! Their demands weren't onerous.
Today distro makers demand that people would do that same work which they still need, but because this work today is needed solely to make distributions happy others refuse.
Especially since what distributions offer (a way to deliver stuff to people who couldn't afford BIX or CompuServe) is no longer all that valuable.
