There is zero chance of the former and less than zero of the latter;
making major, hard-to-test changes in the rather-hypothetical hope
of discovering entirely-hypothetical bugs is not my idea of the way
to run a stable release branch.
Feel free to create a patch for 8.4 though --- I think this is a
reasonable suggestion for making *future* RM development safer.
(Also, if there are any bugs in the extant code, we'd presumably
back-patch fixes discovered in 8.4 testing, long as you don't
whack the code around to the point of unrecognizability...)
