Why would it be harder to keep them flat? Regardless of one-sided or two sided, you should be giving your stone a few passes with a flattener before sharpening.
The headache is just if the opposite side is dished, since the stone has to rest on it while you’re working on the active side. If you’re flattening every time anyway then it’s not all that bad. My assumption is that people aren’t haha
