Picky eating would be another issue IMO. If you recognize a problem, you then evaluate what is causing the problem I.E a snake that is not comfortable being handled constantly (discretion...).
But I can see where you could make the point why wait until a problem comes up to solve it. I do know many people that handle their bps nightly with no feeding issues or behavioral issues. But yes- debatable indeed. I handle twice a week personally, simply because thats all I have time for.
