[webkit-dev] Should we close the tree? (was: Re: the new TestExpectations syntax is landing soon)

Now tracked as <https://bugs.webkit.org/show_bug.cgi?id=97182>.

I think that we should close the tree if resolving this takes any significant time. Not being able to see how exactly tests are failing on other platforms is unacceptable.
