I completely agree. Which is why I believe every rule needs to be followed. How 'trivial' a rule is, is usually nothing more than opinion. And in many cases, it is an uninformed opinion (or at least one not given a lot of thought)
Example: covid. When sports resumed a lot of fuss was made about some rules like not shaking hands after, or players not swapping jerseys after. Why can they be in contact, but not take part in these? And it is a very good question, one that should be explored rather than just cast off as stupid, without given much thought.
And the answer is (was)......I was responsible for getting athletics back up and running in my area, and this is the thought process..... In order to get competition back on line, we had to eliminate all contacts that were not necessary to execute the competition (game, match, whatever). And while not shaking hands after, and not exchanging jerseys after, certainly seem silly on the surface, they are in fact contacts that are not at all necessary to execute the competition, so they had to go. Just one example.
