Onboard glow is extra weight and complications. With a finnicky engine that won't idle without it, it makes sense. But I don't see the point just for safety.
What has worked for decades is a good starting procedure. Do it the same way every time, and don't get in a hurry or start your engine while distracted. FWIW, props very rarely hurt you when you touch them from behind. Since they are pushing, they'll just push your hand away. It's happened to me more than once. It's the tips that will slice into you, and the front of the prop that will pull your hand it or at least stop dead on it.
So as long as you give the prop arc a generous safety margin when removing the glow driver, you really aren't in any significant danger.
