Return status is always a little perilous to depend on in my
experience... I haven't extensively looked at the changes in 0.9 there

Yeah, it's definitely a possible minefield.

And this is a reasonable way to avoid the minefield :)

*nod* Having an extensive contrib is definitely a good way to go for
that and it also gives a way to start testing things, seeing if they
"fly" and if they prove awesome, then they can move out of being just
contrib and being more core.

We ignore it entirely for better or for worse. It's one of the areas
that I sort of want to eventually improve what we do, it's just lower
on my list of priorities at the moment

We send out emails for successful deployments and being able to show
what's changed since the last deployment is incredibly helfpul.
Especially when something breaks.
