Problem is there same one that plagues most open source software. Who enforces or organizes the desktop theming standard that every desktop environment will use? You’re going to have to come up with a universally acceptable method. Are we going to use CSS? Or just some kind of config file? There are many different ways to do what you want, how do we choose one?
My comment explicitly avoids the “standard” problem.
A user could have many "theming system"s installed at once, while only having 1 DE. The user ideally would configure only one, and some program should try to translate that system into the other ones.
Then each app will fetch the list of theming systems the user has installed, and choose whichever the app prefers. And if there’s no match, fall back to a default hard coded theme.
