You don't need to do the full justification on each one, but a

TEST CASE:

#. do foo
#. then bar

helps verifiers find the test case, and goes in the bug description.

So one thing to consider is to religiously keep backward compatibility
with the Juju in r398.  Then we can simply keep SRU'ing the whole of
Juju without worrying about breaking peoples' test setups. This will
require two things I think:

1) Automated integration testing that doesn't change (meaning, make sure
it works on 11.10 release, and that it keeps working in the SRU versions).

2) Testing cycles in between dev cycles so we can invite users to test
with their own setups before we do updates. That can be the -proposed
period, but I think we might want to actually have a week or two of lead
time before we upload to -proposed to catch obvious problems.

I think if we have those two things, the regression potential argument
against features piggy-backing on SRU's can be waived. This is somewhat
like the Firefox process, but perhaps a bit more difficult to keep sane
since one is managing the juju installed on remote nodes, and there is
no defined process for updating the agents.
