It is a better idea for it to store persistent data just as how the player inventory analogy mentions. If it is the same player, then it should behave as if it is the same player regardless of name changes. Can you explain to me why this idea is worse than what is in place?

MC-50247 is for 1.15.2

Also how can this be working as intended? Wouldn't it be better if the same player is on the same team before and after they name change? Changing names should not affect teams that the player is on. The player is still the same person. This is like saying it is intended when players name change to have a whole new empty inventory when they log onto a multiplayer server because they are seen as a different person. Using UUIDs would solve this error.
