That's right. So --changed-use only reemerges the package if the change
only affects your system, whereas -N will rebuild it even if the changed
flag is of no interest to you, such as when a flag you were not using is
removed. It saves recompiling packages for no reason, which is presumably
the reason it was added, it is a newer option than -N.
