I haven't found the time for a proper review, and I can't promise one
right now, so I should probably keep my mouth where my money is, but
here goes anyway: unless running tests is utterly trivial, tests will
not be run, and avoidable mistakes happen.

Case in point: I spent a non-trivial chunk of time yesterday to debug
three regressions clearly visible in iotests.  I did not scold the
people involved in getting the regressions committed for not running
these tests, because I feel strongly I can't demand tests to be run that
require instructions more complex than "make WHATEVER".

I don't think this is "just convenient for development".  I'd say it's a
must-have.
