The current full test suite is punishingly expensive to run, sprint or
not.  Because of that fact, people will defer running it, and sometimes
forget.  Trying to require that people run it repeatedly during a push
race is just Canute lashing the waves.

The rhythm is still broken if devlopers don't run the tests and see them
pass.  Async is an enemy to the process here, because it encourages poor
practices.

Hmm, that hardly seems appropriate, even with the wink.  "Chopping"
isn't violence in any normal sense of the word when applied to
non-persons:  Chopping up a problem is no more violent than chopping
wood or onions (i.e., not at all).
