## What are we DOING?

* Take things that have been unstable for a while and "disposition them".
* Goal: Everything that is nightly only has one or more of the following labels, indicating the blocker(s) to stabilizing it:
* S-tracking-ready-to-stabilize: Needs a stabilization PR (good to go :train:)
* S-tracking-needs-to-bake: Needs time to bake (set a date? other criteria?)
* S-tracking-impl-incomplete: Not code complete or blocking bugs
* S-tracking-unimplemented: Implementation not begun
* S-tracking-design-concerns: Blocking design concerns
* This might be "doesn't quite seem to deliver value we hoped for" or "something doesn't feel right"
* S-tracking-perma-unstable
* Internal implementation detail of rustc, stdlib
* S-tracking-needs-investigation
