I'm confident the "content" property will evolve dramatically in the process to make sure all layouts, even the most complex ones, can still be achieved in CSS without relying on dummy elements.

Bear in mind, implementation interest comes as use surges, and use cannot surge in an environment that's not favorable to experiments. Implementing CSS Regions in browsers will open the door to this experimentation.

This, precisely.  Current Regions is the low-level primitive.
Attempting to design just a high-level primitive (or set of them) will
*guarantee* that useful use-cases will fall through the cracks, and be
unable to be addressed.  For the health of the platform, we *must*
design by starting from low-level primitives to make lots of things
possible, and then adding higher-level sugar on top to make common
things easy.
