I run 23mm slicks on 700c rims on my mtb commuter with Shimano XT 2-pot hydros.
I haven't had an issue, but then I haven't had to panic stop in the wet as I'm hypervigilant in the wet. The rubber I run is the pretty sticky Conti GP4000s Black Chilli. Plus, I shift me bum back behind and below the saddle under brakes (mtb habit) and have panniers on the rear as well, so I get more stopping power from BOTH tyres than most would if just loading up the front. I'm sure the day will come, though.
I like the instant-on feel of the discs - you don't have to wait for the water to be squeeezed out before they bite like seems to happen with rim brakes in wet weather.
