Not even pros generate any significant force on their up-stroke, so don't worry about that. Clipping in has other advantages i.e. more stable and secure foot positioning, but it's certainly not essential for producing consistent power in regular riding. I use clipless pedals on my road bikes and flat pedals on my mountain bikes. I prefer the latter when riding technical trails so I can dab my foot down a little quicker when necessary and not need to keep clipping in and out. On my road bike I prefer the "locked-in" feel of clipless shoes/pedals.
