@lamdbui it would be good to hear what we want this to look like—whether it should be auto-assignment, a label automatically applied to the PR, or something else entirely

I'd start with a label, as it is now. Easy to make a go-link that just shows pending ones.

Quick ping on this - seems like a good thing to land. @lamdbui

Sorry it took a while for me to get to this. Yes, a label sounds great. As long as we have an on-going process for review with say a go/ link as @kaidokert mentioned, we can track this. If we find that we need an alias or something, we can add it later, but let's keep it simple for now.
