0.6.4 is frozen at this point. Just need to get the announcement out. While the team may ask for direct contact at times, we're really overloaded with messages already. That also sometimes means responding on multiple channels, because others don't know what happens in private conversations. If you tag someone in a message, that makes those things more visible to them, which is a balance.
It can also help to explain "annoying" vs "affecting real work we're trying to do.", and what that work is, which may lead to a focus on related fixes.
