If you stop fully, it's not really an issue. Sure, shifting down to first is annoying, but that's about it. If you don't stop fully, it's actually more annoying, because you either shift down to first and have that shock, or shift to second and ride the clutch a bit. Because of that, the few people I know who drive manuals tend to blow stop signs at considerable speed. Personally, I'm more likely to FULLY stop in a manual than an automatic, because I shift down to first, and I don't want to deal with that shock when engaging the gear.
