I noticed though that we need to sidestep the githubv4 library we decided to adopt to pull off this kind of thing. I'm assuming we'll have enough "simple" queries for us to want to keep using the githubv4 tool in the longer term despite having exceptions like this

This is a great point to bring up! Yes, I share your feelings. I couldn't figure out a way to pull off this kind of bulk query with githubv4, especially because of the variable inputs/outputs that are hard to describe with static structs. Go's reflect interface offers us to dynamically create structs at runtime and this could theoretically work with githubv4, but that didn't feel any more cleaner, so I opted to drop down to our old GraphQL interface for this. I still hope that we can figure out how to move all the queries to a single adapter and in the meantime we should keep old-style queries to a minimum.
