Sorry, but I cannot quite parse it.  Perhaps remove "have"?

In other words, raising these includes to the top is not style-only
but is more significant change.  I think these two are logically
distinct changes, but I am fine to see both in the same commit, as
long as they are explained as such.

I would suggest dropping this paragraph.  In the discussion, we
didn't even establish that such a change would be an "improvement",
and in fact, not everything new is an improvement.  If we know
.DEFAULT_GOAL is not used, readers of Makefile do not have to run
around and look for it to figure out what happens when "make" is run
without argument.
