Absolutely. We've also been discussing doing some brown-bag sessions around browser-testing practices as we improve upon them. I think it would be a great way to kickstart inter-team discussion around difficult test patterns (e.g. inter-wiki or multiple-user interactions, etc.), how they're currently being solved, and how we might adapt those solutions to be more portable/isolated/deterministic.

Also, I have to say that delving into these repos has been a great on-boarding experience for me. What better way to learn about the core features of MediaWiki than to be tasked with verifying the specs? So, thank you!
