I don’t have a strong preference, since it ends up in my email inbox either way. But I do think GitHub discussions offer some more options for organizing threads, and it’s nice to be able to easily link to issues and milestones (and even turn discussions into issues when that is warranted). Since LPF work is already happening on GitHub, it seems like a natural fit. But like I said, I’m happy to stick with the Google Group if that’s the path of least resistance.
