[PATCH 0/2] [RFC] Switch default merge backend from recursive to ort

This is an RFC series designed to spur feedback about switching the default merge backend (reviewing the patches is of secondary importance at this point). Some questions:

 * Are there things others want before this series is considered for
   inclusion?
 * What kind of timeline do others think is reasonable?
 * Would it be beneficial to let this series sit in 'next' for an extended
   duration to gain more feedback?

Some potentially useful context in relation to the above:

 * I've personally used the ort backend for well over a year
 * I have ~50 testers using ort as the default merge backend since Nov.
   2020.
 * ort fixes known bugs in recursive, and there are no known regressions
   (more testers may change that)
 * ort is significantly faster than recursive
 * ort provides one new feature already, and enables more that are on the
   way
 * The commit message of patch 1 has more details about the last three items
   above

So...thoughts?
