Why not? Please explain.

You make it sound as if the testers have tried to skim over the several of
dozen bugzilla ticket descriptions linked at
in an attempt at trying to find out _what_ the update touches.

A fundamental problem here is that even if a tester confirms that the
update fixes a _single_ bug, the other several dozens of changes could
cause regression -> reason to be careful and test this thing a bit longer.

That has been easy once the update arrived here on the nearby mirror.
"setenforce 0 && repeat previous command that caused strange behaviour"
is a very common troubleshooting thing, even if there haven't been any
AVC denied messages.
