But this is exactly the opposite; the patch that broke things is in
the 'release branch' (3.3.1); it's not in upstream (3.3). Sure, it's
also on a later upstream, which is also broken.

But then are you saying that if upstream is broken (3.4-rc2), then
stable should be broken as well (3.3.1), and remain broken until
upstream is fixed? I fail to see what would be the point of that.

And why do you think the same would happen here if *one patch* is applied?

Plus, git is developed this way; and yes, you might say the gates are
opened when there's a new non-maintenance release, but the same
happens in Linux. It's not the rule of 'first on X' branch that keeps
the gates safe; it's the amount of patches.

So, in your mind "correct" is "never ever do an exception", even if
this strictness leads to less stability. If the objective is not
stability, I would call this the 'backports' tree then, which might or
might not lead to stability.

Rules are not perfect, why not add a new rule "It reverts an earlier
patch to 'stable'.", then you would be both following the rules, and
ensuring more stability :)
