In support of #426. There's still a little bit of surrounding framework that expects these decision files, but I'm trying to split out changes.
Note I'm dropping affirming/abstaining, as well as the accepted date -- I'd be happy to copy-paste decisions into comments on PRs if it'd be helpful, but I thought maybe we could drop those from the repo given they aren't asked for in on new proposals. If we change our minds, we can always look at git history too.

following the [roadmap process](/docs/project/roadmap_process.md).
