> It would be great if you could install Qt 5.9, 5.12, 1.14 in parallel and have apps use the latest version (except for that one app that triggers a bug where you fix it to 5.9).

The underlying library-loading system on Linux handles this just fine, and has for decades (look up "soname" for details).

The problem is that system package managers want to load "just the latest" & maintainers have to take extra steps to enable loading of multiple versions.
