The renaming moves from a document design perspective (high level) to an
implementation one (low level). The use of those variables, however, is
inside of the layout block which is supposed to be a document design
specification.
It also moves from an essentially one-dimensional parameter realm
"above-x, between-x, below-x, above-y, between-y, below-y" to a
two-dimensional matrix "between-x-x, between-x-y" ...
This does not make it feasible to introduce further layout components
for spacing since the parameter growth becomes quadratic.

If the naming scheme is tightly coupled with the limitations, any
resolution and/or improvement would require a complete overhaul of
existing layout specifications.
So I don't see this change of the naming scheme as a change that
encourages further work on layout specification improvement.
