Reset view roll operator

view3d.view_roll only allows adding or subtracting from the roll angle, but not setting it to 0 to reset. The only way to reset the roll I found online is to go to orthographic view and then re-orbit back to where I was looking before, which is needlessly annoying. I just want a shortcut to reset the view roll to align to the horizon :(

Also, is this still the place for feature requests as docs suggest? Because it doesn't seem that active, and blender's issue tracker has a bunch of feature requests under Type: Design label, but I didn't want to go against recommendations and post it there.
