People do bits & pieces from time to time (I did some when I started
contributing) but no one's currently making any broad plans to change
the world or anything.
(related to StringRef-izing is also ArrayRef-izing. In my opinion the
latter (ArrayRef) is more obvious. The former can be complicated by
the existence/use of Twine & its applicability in certain calls - but
maybe that was just me overcomplicating the problem)

The general policy of development is small iterative changes on trunk.
Very rarely is there justification/need to branch.

For something like StringRef-izing a simple "make check-all" (actually
the check-all target is from the CMake build, not sure what the
autoconf+make targets are, it might be the same in this instance)
should suffice. But if you're curious there's also the test suite
(details of the various testing layers can be found here
