Yeah, unfortunately no Linux distros are ever willing to do major
compiler upgrades, even Fedora is only willing to take minor compiler
upgrades, so our willingness to support old compilers is proportional
to the size of our user base eligible for updates. :/
I understand resistance to restoring support for a compiler we
previously decided to drop, so let me tone down my request: I just ask
that when we decide to drop support for a compiler, we consider which
major distros actually shipping our updates still use that compiler, so
we can get a feel for how many users will stop getting WebKit updates
as a consequence. We've just recently gotten to the point where a few
distros are beginning to take our updates, and I'm really hoping to
facilitate this by maintaining support for the compilers these distros
are using as long as possible.
It's really annoying to be stuck catering to older compilers, but I
don't see any good solution to this without throwing users under the

I'm not aware of any distributor that has ever attempted to seriously
backport security fixes; not even enterprise distros like RHEL do this.
Reality is that distros only ship what we release upstream.

Nobody ships trunk, they ship our stable releases, which branch off of
trunk every six months. We don't have the resources to maintain
compiler support outside of trunk.
