Just a bit more on this: so what do you think should happen in the
example I quote here of a transport that can't set permissions?
(Suppose it is one like DAV where (I think) there's just no way we
could add it.)

I feel a bit uncomfortable having it just silently return as if that
feature had been tested.    Even though this is distinguished from
"things we can/should fix" I like seeing that some things weren't run
and why.
