> If you like to tinker with your own system, that’s fine with us. However, if you change things like stylesheets and icons, you should be aware that you’re in unsupported territory. Any issues you encounter should be reported to the theme developer, not the app developer.

It is unreasonable to expect each end user to build their own custom themes, it makes far more sense for distros to do the work once.
