Isolating functionality into more layers of a protocol can
make a design more manageable relative to fewer but more
complex layers. Of course, adding layers does tend to have a
performance cost. (Later tuning can virtualize or merge
layers or even migrate functionality.)
Just restating the obvious, I suppose.
