I don't know why the powers that be muck around in football so much. It's like they feel like they've got to do something, so just do it. The only worthwhile change in my lifetime was to introduce the back pass rule.Yet the powers that be love to change everything to favour a new style of play. The offside law has changed so many times, the handball law with the crazy drawings is another one and constant tweaks as well as bringing in VAR or not depending on what league or competition you are in and what round of said competition you are playing in. I follow Rugby Union and although teams do adapt to the referee especially when it comes to scrums, certain nationalities will favour certain things and you tend to see French referees if you lose a few scrum penalties against you, they will just keep being given.
Rugby Union just seems to be constantly trying to grapple with how to maintain rules from the amateur era that they feel is in the DNA game, whilst have it played by professional 18 stone plus athletic monsters. The answer is you can't without making it excessively complicated that's a turn off for the casual sports fan
