I think this is a much larger change, since it ties in with other code changes
to e.g. remove the distinction between smbtorture3 and smbtorture4.

Perhaps we should hold off on this as part of the test infrastructure
improvements, though I agree it would be a nice thing to do in general.

Any news on this?

This is done :)

It would be good to improve the formatting further. At the moment, if I just run one test I get 9 empty lines.
Can we output the unit of the test durations? (e.g. seconds)

Nothing has happened on this as far as I know.

This is in progress; I've got some changes that update our in-tree subunit to
version 2. We'll still use subunit1 output internally (by converting v2 output
to v1 before we parsing it).

Still some work to do here, especially for the pidl tap tests.
