Some players tend to get really ingrained in Their character and que includes making feats for what Their characters might naturally be good at. For example, a character with a law and order background might have a feat that gives them unfettered access to local law enforcement where they have a reputation. If your players come to you with feat ideas or reskins, then have a conversation with them. Ask them why they came up with the feat that they did, and work with them to make any changes you need to be made for balance. Unless a feat is horribly broken, there's no reason why you wouldn't be able to incorporate them into your game.
