You can use the clutch normally as you said. The only issue is if you lightly bump the shifter with your foot or forget qs+ is enabled and go to preload the shifter out of habit... Obviously that is rider all dependant and it sounds like plenty of folks never run into that problem. I found it happening rarely but often enough that (for me) it was better to just leave it disabled and not have to learn new habits. Whether that's smart or lazy is up for debate, lol. Regardless it's what works for me.
