OS package managers make two assumptions:

- that packages follow semver

- that the OS packagers are in a better position to test package combinations.

If the author releases a new version of libfoo, and A, B and C in an OS repo depend on libfoo, then the OS packagers do not release a new version of libfoo until the tests for A, B & C pass.

These are two good assumptions, and the language package world would be in much better shape if they followed those assumptions too.

Which OS are "OS package managers"? There is a world out there greater than GNU/Linux.

Cargo assumes the former.
