Real Tokens for CSS Path

It would be nice if we could use real Tokens for the CSS path (if defining a custom stylesheet) so that if anyone needs to do any weird logic in the path, like a different file based on the current domain, or some other completely random idea, they could simply create a new Token or use one of the many existing tokens instead of the limited few custom tokens provided by the Wysiwyg module.

Given that the majority of Token is in core it's not going to add any extra dependencies, and the Token Tree could be added if the Token module was present.

I'd be happy to write the patch if I get some indication that the idea would be accepted in some form.
