This will either take 5 seconds or 0 seconds to run; it never hurts to
just call it anyway.

I'm not following the logic in this thread at all. Won't this be a
problem for all of like 3 days here when the pacman version in
[testing] vs. non-testing is different? And after that who cares? Or
you could just upgrade your chroots and system to pacman 3.5 and it
wouldn't matter either; this package depends on nothing else in
[testing].

Eventually, but there is this crazy thing called backward
compatibility that we have to take into account...
