If they are tight enough, I don't think bands are purely cosmetic. If they are loose, clearly they offer no support to the drum. I just had 7 cracks fixed on a 32 year old bandless oak Valje. While 2 of my 4 Skin on Skin banded oak drums have cracked and been fixed, each had only 1 crack, and neither has cracked again after over 20 years. Both SoS that cracked were finished with Watco oil and no polyurethane, the 2 that did not crack have polyurethane finish. I live in NJ/NY where the annual hot cold cycles cause major seasonal changes in humidity.
Now on all my drums, I wait until mid winter dry season when the wood shrinks and move the bands so they are tight and put the screws back in. In the summer, the bands get really tight, but they stay tight through the winters as well. I think the Valje cracked in so many places partly because it had no bands or alma, and oak shrinks and expands more through the wet/dry humidity cycles of NYC. Incidentally, none of the 5 banded cherry SoS drums I know of have cracked over a 15-20 year period. Jay Bereck told me he started using cherry because it has the lowest coefficient of expansion with humidity of all the common woods.
