FYI in case you aren't aware, the rewrite was shipped, and then had to be reverted due to issues being discovered. That's "Jarred's high quality bar" you're so confident in.
Can you link me a source that says that the rewrite shipped to a point release (not canary)? I'm not seeing this.
News to me… share a link?
The whole point of having canary builds is that they're unstable. That's why they're called canary. Rockets failing in test flights isn't a bad thing.
