The change to mesa isn't fedora specific. How and when we test and
integrate that change (and other large, potentially breaking changes)
with the rest of the software in the distribution is what's fedora
specific. That's what needs to be discussed on the list, and it's why
the change process exists.
I fully agree, but my response was not to an email arguing about timing,
but one questioning the legitimacy of the change and the level of community
vetting it had seen.
