Nor would I. It's one thing on any rig if the scope needs to come off. You're dealing with just two attachment points in most cases. If you're going beyond that, you'd just as well disassemble the whole thing and re-torque everything back up while you're at it - and there's usually a reason you're disassembling beyond removing the optic anyway.

Most ARs anymore come with the rail integral to the upper receiver. There's no additional height added on its account. Not so with a stock bolt gun. A Leupold-style base is still going to add some height, but not as much as the rail will. I still pay attention to things like cheek weld though, so maybe I'm just a little bit old-fashioned?
