I have never understood why people put so much stock in icons. It's like people getting upset over the new pixelated reddit icon. It's all reminiscent of the custom ring tones and call back song that people used to obsess over.
I like clean looking UIs with consistency, having an app that has a windows 95 looking icon while the rest of the Home Screen has icons that are at least in the same design language looks off
It’s basically the same kinda shit in real life, maybe you personally have a beard and like the way it looks while others think it looks like crap, insert basically anything in life, wall paint, cars you like etc..
But the beard and your clothes are all things you control. You don't expect someone to change their looks for you. So likewise you shouldn't be expecting developers to meet your stylistic demands.
