It wouldn't be significant change to Fighting styles themselves.
However with Blind Fighting, Thrown Weapon Fighting, and Unarmed Fighting, it is clear that either they assumed DM would make those ruling or they completely missed those
Fighting styles were designed to be mutually exclusive. For example, Dueling not working with Great weapon Fighting or Two Weapon fighting despite no way to get 2 fighting style except via Champion.
However WOTC didn't realize that you can't draw enough thrown weapons to attack with all your attacks or that fighter unarmed attacks were woefully weak. But they didn't want to make errata. So they patched it with Fighting styles.
When they redo the PHB in 2024, that will be their opportunity to errata thrown attacks, unarmed attacks, and maneuvers.
