There is NO downside. Hydraulic brakes have been around so long that mfgs will use the optimal piston sizes for braking power and modulation. With both cable-actuated hydraulic (eg. HY/Rd) and full hydraulic brakes (eg. R785), there is enough reach and engagement adjustment at the lever stroke is appropriate. I've used over a dozen hydraulic brakes and lever stroke length has never been an issue. Here's a typical review on the Hy/Rd:

"The HY-RD definitely outperforms any mechanical disc brake Iíve ridden, surpasses TRPís own Parabox brake system, and comes close to the Formula R1-based 324 Labs system weíve spent a good amount of time on. It also looks a lot more elegant than any handlebar or steerer tube-mounted system, at a weight competitive to the popular standard, the Avid BB7 mechanical disc brake. (CX manazine):"
