I totally agree with your view point on CCK's display fields tab, and
the field_group module. They're only remedial examples of what is
possibly and should have a scope much wider than CCK.
I just feel that you approach tends to cater to designers that think of
design in a page by page manner, instead of a collection of widgets with
many potential layouts. Then again I may be completely mis-understanding
your idea, after all you did do that panels thang :).
There are also technical merits to drupal_render that I wouldn't want to
see lost... the most important one for me is the potential for caching
Creating a central pipe line for the processing means we have a single
point of focus for caching based optimizations and process improvements.
Personally, I'd like to see it become capable of caching branches in the
render array tree in various states including built abstraction, altered
abstraction, processed abstraction, rendered abstraction. It at least
seems like it would be fun to experiment with.
Since the DataAPI and FormAPI extend the model, they too would probably
benefit over time as we gain more expertise with it.
