True, its a matter of preference. Some people like RGB and colors, I like black and little to no LEDs. I do care about the type of switches. My primary reason for this is my wife does not like noisy mechanical keyboard. But while I'd spend money on such, I would not spend money on custom keys. However, you are right that these do exist, and as such a sticker to create a custom key seems a valid minimal mod. Good luck with your business!
