They *are* a bandaid, but a reasonably well-working one. Hopefully we'll
an even more robust Nix-like approach soonish:

That doesn't solve the diamond dependency problem, but hopefully
there'll also be a solution for that at some future point in time
(Backpack). I'll also note that I personally don't know of *any*
software platform that has actually solved this problem entirely
satisfactorily. On the JVM, OSGi gets close (at least in theory), but
AFAICT it's a lot more complex that it (ideally) should be.

Indeed, but my personal experience is that it actually doesn't happen
very much in practice. (Anecdotal, I know.)

Meh. Speak for yourself! :)

Personally I'm more interested in repeatable and consistent package
installations rather than avoiding 30 minutes of 100% CPU usage once in
a while.

(Of course, priorities may vary and reasonable people can disagree!)
