> Your system package manager typically also sucks for keeping multiple versions/variants of libraries around They really don't. At most, what really sucks is the way some projects are bundled.

Qt ships and maintains multiple release versions concurrently, and it's a shame that package managers insist on pretending they only need to have one semver major version installed at all times.
