Should Rehydration Limit Become Mandatory For Every Fight On Earth? Global Standard?

The rehydration limits below heavyweight try to level the playing field by ensuring fighters enter the ring as close to each other in weight as possible which means that a naturally larger fighter is restricted in how much of a weight advantage he/she might have in the fight. Although the larger fighter still often has a weight advantage because of the time gap between the same day weigh-in and the fight itself, the rehydration limit reduces the amount of potential weight gain. Due to it being recognized as one of the fairest weigh-in procedures possible, certain sanctioning bodies have stipulated in their own rules that rehydration limits apply to their title fights, but why stop there? Why should only a title fight be a fair a fight as possible? Is it time that the rehydration limit is implemented throughout boxing on a global scale to become standard practise for every boxing match that takes place from this day forth, in order to ensure the fairest fights possible and to prevent boxers entering the ring with a significant weight advantage over their opponents?
