The point of it is that the release branches are actually used by GCC users,
many people don't use just official releases, but arbitrary snapshots from
the release branches.  If a potentially risky patch is applied immediately
also to release branches and soon needs follow-ups (happened many times in
the recent history), then that results in unnecessary breakage.
Of course for lots of simpler patches that aren't deemed that risky waiting
before applying is not needed, but I think this patch wasn't such a
category.
