I understand Robert's reasoning to split out the core changes (as
denoted above). However, I *would* tend to follow on with an
additional subsequent patch that has the rest of the content as it
cleans this area up (as opposed to dropping it all together). It
makes the code a little clearer and is basically little to no risk (no
functional change).
