Should the NCAA change spring practice rules

DISCLAIMER: I know nothing about football.

Reading the rules about spring practice and preseason. What logic is used to write those rules? I understand the safety component with the contact limits. Would it benefit teams in the transfer era to get some more practice time together during spring to gain familiarity? Or would that completely blow up the logic behind the rules?

Here’s the rules

Preseason
Teams must allow a 7-day acclimatization period for new and returning players. During this time, players can only practice once per day, and each practice can't be longer than three hours. Players must also get at least three hours of recovery time between practices.
Contact practices
During the preseason, teams can have up to 12 contact practices, with no more than four live contact practices per week. Full contact can't happen until the third practice.
Spring practices
Teams can practice for up to 34 days, with 20 hours of unrestricted activities per week. Players must get one day off per week. No more than 12 practices can involve contact, and no more than three of those can be 11-on-11 scrimmages
