In a GitHub project I've contributed to (dolphin-emu), a compile check for all supported platforms, plus a few tests, shows up next to the big merge button. So the "other party" doing the merge is a robot, and you can still click the button.
I haven't been a committer on any other large GitHub projects, so I'm not sure how common this is.
So, sadly, I don't contribute to really any github projects. This is a new feature to me and does go a long way to addressing my concern. Honestly, it may completely address it. Certainly sounds like it does.
