Since I've already broken E-D-S APIs across the board for 3.5.3, I'm
following up on this as well.

Same plan as what I originally sketched out, except I'm skipping the
deprecation phase and moving straight to #error since there's no point
drawing this out, and I _am_ bothering with the backend libraries.  It
turns out to be nice for backends to just have one #include.
