I didn't pipe up during the PTG discussion because a) I missed the
first 5-10 minutes and hence probably some important context, and
b) I've not been a nova contributor long enough to be well-informed on
this topic. Apologies if that was the wrong decision.
But I do have a few thoughts on this, which I'll share below. Given
b), take them with a pinch of salt ;-)
Firstly, I was impressed with the way this topic was raised and discussed,
and I think that is a very encouraging indicator for the current health
of nova contributor culture. We're in a good place :-)

+1 - I'm not wildly enthusiastic about the "keep it undocumented"
Here's my stab at handling some of the objections to a written policy.
>> - The rule should not be documented (this email notwithstanding). This
>> would either encourage loopholing
I don't see why the presence of a written rule would encourage people
to deliberately subvert upstream trust any more than they might
And a rule with loopholes is still a better deterrent than no rule at
all. This is somewhat true for deliberate subversions of trust (which
I expect are non-existent or at least extremely rare), but especially
true for accidental subversions of trust which could otherwise happen
quite easily due to not fully understanding how upstream works.

I don't think it has to. It's not a legal document, so there's no
need to attempt to make it like one. If there are loopholes which
can't easily be covered by a simple rewording, then so be it. If the
policy only catches 50% of cases, it's still helping. So IMHO the
existence of loopholes doesn't justify throwing the baby out with the

I agree that enforcement would be difficult and awkward, and that we
should be able to trust cores. But in the unlikely and unfortunate
situation that a problem arose in this space, the lack of a written
policy wouldn't magically solve that problem. in fact it would make
it even *harder* to deal with, because there'd be nothing to point to
in order to help explain to the offender what they were doing wrong.
That would automatically make any judgement appear more subjective
than objective, and therefore more prone to being taken personally.
