as @Menion mentioned we've already created some improvements in the official MapsForge render and adopted "cubic" or text and symbol orientation.
I also like the scale-font or scale-symbol directives but I think it doesn't fit the conception of theme when only the "rule" should specify the appearance of a particular element.
bg-rect-* are also a little bit strange and were created especially for our use-cases. Anyway, I've already thought about adopting of the "Shield" system used by Mapnik https://github.com/mapnik/mapnik/wiki/ShieldSymbolizer
It's basically a combination of image and text - especially used for highway number shields.
