Revisit the Constraints

I just got back from the Ember Face to Face this weekend and I was reminded of a core value that I believe in: Revisit the Constraints.
In order to avoid constantly re-litigating every decision from scratch, communities create shorthands for conclusions that they have already arrived at. These shorthands can ossify into rigid ideologies, which eventually weigh communities down too much, allowing newer communities with more modern assumptions to quickly leapfrog them.
In order to avoid getting swept asunder by these new communities, we need to revisit the original constraints that led us to believe that we needed a custom class system. This may require a willingness to revisit long-standing and important mental shortcuts ("we need our own object model" avoids constant re-litigation and allows a community to build on top of shared assumptions), which can be painful.
If you Capture the Constraints in the first place, it makes it much easier for the community and its leadership to decide when to revisit stable, core assumptions. That doesn't necessarily make the transition painless, but it does focus the conversation on inherent conflict rather than the incidental conflict caused by ideological disagreements.
