FWIW I've noticed this happening a lot more than twice, it's more like once every 1-2 days. I don't understand what Graphite is doing there but is it possible that for a brief moment, the diff between your branch and the target branch (which in this case isn't `main` IIUC cause you're stacking PRs) has tons of commits, hence the auto-subscribing?

It would be really nice to figure out why that's happening since I think a lot of people are getting regular spam from Graphite.

@arsenm  When you say a "reorder", do you know how Graphite implements that "reordering" in terms of more basic Git operations?
