I wasn't talking about the tree's status quo here as it shouldn't
impact the discussion. Just because the tree is red, doesn't mean it's
the right thing (tm) to just drop the towel and make it more red (even
if we seem to agree on the badness of that :)).

To add some thoughts here, saying that the tree is red covers several
states (failing tests, not building...) and IMHO the EWS has at least
helped on the building side. As far as the tests goes, a lot of
platform differences are unfortunately uncovered on the bots.
