On the contrary, I should say: very common. We have hardly any control over
what is installed on the application servers at our university (let alone
how well it is installed).

Then what about new features that don't depend on parallel? Maintenance hell
is born, just because you effectively force somebody to fork (True, the R
builders are not the ones forcing people to stay on some "old" version, yet
this scenario is not that strange that it should be ditched without regard).

Somewhat silly if it only depends on it because of the check, no?
