We also considered a similar idea. There is indeed an experimental
implementation of area blocks macro (a_blocks_SKBB_ in the file
thArea.mp) which allows not only density and size setting, but density
and size may change along specified direction (there are 5 arguments:
direction, starting size and density, ending size and density).

It is perhaps too complicated and simple density/size settings (for
all randomle generated areas) would be sufficient. What do others
think?

We intented point symbols to be just symbolic representation of
passage fills. If there is a rock which is important for orientation,
it should be drawn precisely as line brock-border, otherwise it is
enough to give information that some blocks are there using point or
area blocks symbols. (In addition point symbols can be scaled using
-scale option).
