SD is a one to one replacement of the existing scheduler guts - with a
different behaviour.
CFS is a huge step into a modular and hierarchical scheduler design,
which allows more than just implementing a clever scheduler for a single
purpose. In a hierarchical scheduler you can implement resource
management and other fancy things, in the monolitic design of the
current scheduler (and it's proposed replacement SD) you can't. But SD
can be made one of the modular variants.
