I do a lot of bore cutting, so off they come. Also when sharpening they should always be below the rakers as you said, and even the anti-vibe humps get in the way of filing the rakers, how much more the actual safety humps. Regardless, I don't run the one with safety humps, but the ones with the smaller anti-vibe humps are no problem and to not typically slow boring.
Look at how much extra filing was involved just for the anti-vibe humps
, while they don't slow the cut(for average cutting), it's more time per cut when you have to mess with this crap.
Look at the one by my thumb, that's a lot of extra filing.
