I'd like to lend my support to the value of "authoring WPT tests and
WebKit patch at the same time".
A month ago, I looked into what effect 2-way sync had in Chromium, and
"Chromium contributions have more than tripled, and it seems very
likely that automatic export of changes has something to do with it."
Gecko is now improving its sync with web-platform-tests, and frequent
sync with WebKit is at the very top of my wishlist for things that
would enable improved interop of browser engines.
