I am willing to accept the argument that non-incremental testing is
simply not viable for performance reasons.

That being said unless you guys volunteer to fix the tools I am in
strong disagreement with everything else that was said.

It is true that in theory what we have works IF everybody does the right
thing, but that's beside the point. My point is whether it works in
practice and I do believe that there is ample evidence that it does not.
If every removed test requires several emails going back and forth,
people getting LOUD and days of turnaround time then to me there is
something wrong. As it is the system is too brittle.

The system might be fixable but unless somebody has the resources to do
it it's a moot point.
