In this particular case, however, I suspect that, if they'd been using a centralized system, it still would have looked like a fix was needed for earlier versions, but that impression would have been correct. A decentralized system makes it feasible to use a process which prevents bugs from affecting releases that one would expect them to affect. Even aside from getting the analysis right, it's hard to say that, when it looks like a bug affects several releases, you'd rather it actually affect all of them than turn out to have been excluded from them.
