This is why we've started to write down larger decisions, the reasons and spots of uncertainty for these decisions in a central, public place. I'm jokingly referring to this as our growing constitution of tech.
I think this is right, because some of these decisions are not entirely comfortable, but a lot of bright people have thought about this over time and this compromise is what we figured is the most effective and workable one.
I'm entirely willing to up-end one of these decisions, but only if something strong comes up that hasn't been discussed in the past many times. But, our reasoning is here, and everyone can take all time they need to make a case why it's wrong, or some case needs further consideration and detail.
