It's probably faster because the copy operation is skipped when the
files are identical, but otherwise the results should be identical
(modulo the updated mtimes).
If so, putting "INSTALL=install -C" in /etc/make.conf accomplished this
easily. The problem is that there's currently no way to turn off the
hardcoded -C in some Makefiles.

That's an approach I hadn't considered, but it feels more heavy-weight.
