Root rot is caused by too much water that displaces air iin the soil, which creates an environment where aerobic amd desirable microorganisms can't thrive, and the harmful ones that cause root rot can thrive. As long as the soil is constantly moist, and healthy with good aerobic microorganisms and air in the soil you shouldn't get root rot. Banana roots, and most other plants, should NEVER dry out, and constant moisture even in winter is optimal, as long as there is sufficient air in the soil and it isn't water logged which turns it anaerobic. With a properly designed Wicking tub, with an air gap above the water and a breathable membrane the underside of the majority of the roots will air prune and secondary roots with more efficient nutrient uptake will be triggered to grow. As long as the mass and majority of the Banana plant roots are not flooded, a few that creep down into the lowest wicking point of the soil will just die, but the majority of the roots will be above in the ideally moist zone and be fine. From my research, a self watering wicking and air root pruning grow bag/tub in theory can definitely work well with Bananas if done right. I have a Dwarf Cavendish in one right now I'm experimenting with. We'll see how it does.
