So, I want to be careful not to descend too far into reductionism.
Nobody is suggesting that an architecture WG goes off into the corner
and applies theory to problems without practical application.

However, some things aren't measured in how fast, or even how reliable
a piece of code is. Some things are measured in how understandable the
actual code and deployment is.

If we architect a DLM solution, refactor out all of the one-off DLM-esque
things, and performance and measured reliability stay flat, did we fail?
What about when the locks break, and an operator has _one_ way to fix
locks, instead of 5? How do we measure that?

So I think what I want to focus on is: We have to have some real basis
on which to agree that an architecture that is selected is worth the
effort to refactor things around it. But I can't promise that every
problem has an objectively measurable solution. Part of the point of
having a working group is to develop a discipline for evaluating hard
problems like that.
