I've worked with regular CSS and I'm sure that stylesheets offer just as many customization options as things like QtCurve or QStylePlugins. The reason that it may not seem this way is because Qt didn't document regular CSS syntax in the documentation for stylesheets.
I can't verify that stylesheets can do everything that a style plugin can do, but I know for sure that Breeze can be made using a qstylesheet so there shouldn't be any reason to say that stylesheets don't have enough features to be added to KDE.
