But surely you are also spending a lot of time with the system in a state that
no sane programmer would ever have chosen ? If so then (3), (4), (5), and (6)
are all moot.

Come to that, I don't see why (7) follows.

(2) seems dubious too...

Which leaves (1) unchallenged -- can you explain what the actual value to me of
(1) is ?
