I think that's a rather strange conclusion given that I've submitted a
parallel series that makes some of those failures easier to diagnose
than the same changes in this series. I.e. the failures in build
v.s. test phases, not the individual test format output (but those are
orthagonal).

I think it's a fair summary of our differences that we're just placing
different values on UX responsiveness. I'm pretty sure there's some
amount of UX slowdown you'd consider unacceptable, no matter how much
the output was improved.

Clearly we just use it differently.

For all the flaws in the current output there are cases now where you
can click on a failure, see a summary of the 1-2 tests that failed, and
even find your way through the right place in the rather verbose raw log
output in 1/4 or 1/2 the time it takes the initial page on the new UX to
loda.

I think it's clear that we're going to disagree on this point, but I'd
still think that:

 * In a re-roll, you should amend these patches to clearly note that's a
   UX trade-off you're making, perhaps with rough before/after timings
   similar to the ones I've posted.

   I.e. now those patches say nothing about the UX change resulting in
   UX that's *much* slower than before. Clearly noting that trade-off
   for reviewers is not the same as saying the trade-off can't be made.

 * I don't see why the changes here can't be made configurable (and
   perhaps you'd argue they should be on by default) via the ci-config
   phase.
