Strongly agreed.
And if we don't have a community commitment to do that can we please be
honest with the world and tell everyone that when we look at the cost of
this issue it was something our community did not choose to pay?
Being ready to explain decisions (or positions) is fine. The problem
was the word "justify". When do we know that a decision is justified?
Who decides? That's an undefined metric. WG decisions are explained,
and critiqued, all the time, by everyone.
Personally I hope we don't develop too "mature" a concept of what
we're including in pervasive monitoring, because we need to be open to
new ideas all the time. Therefore I hope we never develop criteria by
which a PM consideration could be "justified".
Note however that I do not want ADs pushing back at the end of the
process (unless WGs clearly failed to get adequate review of their
architectures up front.)
(Aside: That's circular -- unless the critique is based on new ideas
that emerged between WG last call and a telechat, then by definition a
late critique of an architectural issue means it failed to get
adequate review at the proper time.)
I want ADs to be pushing back in the early architecture phases.
Comments on early architecture drafts, and WG-decision-level appeals
filed early in the process are probably better tools for pushing back
on WGs that are not adequately considering privacy than late-stage
discuss positions requiring architectural change.
Yes, and we encourage that with the paragraph as it is, without "justified".
And as Eliot points out, the question of what balance in tradeoffs is
appropriate will evolve over time. At the beginning if a WG does a good
job of considering something and you just don't like how they balanced
the issues, your only option is to start a broader discussion. That's
how it should it be. If community norms emerge, then there are tools
for applying those.
Yes.
Do we have agreement?
