That is the goal, once all the front-ends have been converted and
regressions fixed.  I'd wait a little bit (at least a couple weeks)
for things to stabilize and for people to get comfortable with the
change before ripping the old code out.  (Doing so will allow
simplifying and cleaning up more than just removing the conditionals.)

Nope.  I'm hoping for others to provide those.  And ideally help with
performance profiling and tuning.
