The latest version is not necessarily reliable, give the developers of other components a break, they also need to explore new approaches. Converging on a common version means a lot of people found this particular version reliable;

Static building is the opposite of using the latest version, people use the latest version *at the time they bother to check* and then lock it down and accumulate technical debt. People do not like making the effort to update, period, they can’t complain using dynamic libraries forces them to update on a regular cadence (that would expose that they do not want to make this effort) they complain that the update forced on them by distributions is not new and shiny enough.

That's only true for forges like PyPi or crates.io. Where people are free to pick any version they like.

With distros is the exact opposite: few packagers, often just one, single, person decides what version of library to package.

That's the opposite of the process that may lead to the outcome you describe.

Still better than some random version that was picked by god-know-who for god-know-what reason and which wasn't even tested in conjunction with app.

People complain when something doesn't work, period. It may be too new or too old or anything in between.

But with distros they are often in position that they have no one to even complain to because person that assembled the crazy combination of libraries that breaks things is not even result of conscious decision, but more of result of random dice throwing.

According to the distro makers every package should be ready to work with every version of library… but that's rarely a thing that any sane developer would accept: to know whether something works or not you need to test… and distro makers make that exceedingly difficult.
