yeah, in fact, really only the header size has been introduced into core now.
All other functionality we could simply set using an input_boolean or a template is lost on us now (well not exactly now, because it still completely works, but officially it is…). Which is a true bummer.
as a matter of fact, I’ve just posted a small thingy on the card-theme thread of card-mod. Which isnt anywhere near the functionality of CH of course, but the only thing we have for now.
Really hope we can have the Options options, the exceptions, which you are referring to here and the builtin variables back, anytime soon in a new custom add-on, or preferably core of course.
