Right, I'm totally aware of that solution because it has come up in the
past. Chromium implemented a similar solution (presumably
Cr-Commit-Position is that thing?).

What we need is a concrete plan to add the support for such a mechanism in
WebKit and update all the tools we have: buildbot, webkitpy, etc...

As far as I can tell, nobody has yet to propose such a plan for WebKit.
THAT is the biggest blocker as far as I can tell.
