This is basically what I was thinking of. I couln't find an argument
for needing more than 2 tiers in the expansion process, but what I was
describing is certainly generalizable. So precisely why do you think
one needs to distinguish "authoring semantics", "typesetting style" and
"fine-tuning"?

This is clear. Question: how difficult would it be to extend TeX to
allow for dual/multiple tier expansion? What are the draw-backs?
