Assorted Prefactors for cause/effect tracking

These are some mechanical code rearrangements that are
separated out to reduce noise in later CLs. The goal is
to reduce the amount of plumbing a little for the next CLs
but more-importantly, make the really broad plumbing CL
"trivially" mechanical given its sheer size.

Changes here focus on:
 - Extracting transition instead of proxying through controller
   in some cases.
 - Splitting up methods which can have lifecycle effects
   based on some parameters into methods that do vs
   methods that don't.
 - Removing unused overloads
