While this doesn’t solve all testing scenarios (e.g. this doesn’t test a macOS or Windows-related change due to the added hours it take for a PR to be “green” when run on Travis for macOS or AppVeyor for Windows)

Just an FYI, I was talking to a friend in Travis and he suggests in the next few weeks they’re going to get a lot more macOS capacity. We might want to try this again in a few weeks and see if their new capacity is enough that the lead time is good enough.
