Define users. If compiler developers, your argument holds. For other
users who just want a stable compiler, the argument does not. As for
FSF gcc, I disagree. If an egregious  regression in an important
benchmarks is discovered, in general they would escalate it to a P1
and most certainly fix it before release.

Especially when the problem is understood and a fix is at hand.
