And then, when the original file changes, you lose the improvements and
you might even end up with a broken system.

For example if a systemd unit file is updated to match a change of
behavior in a daemon. Say, from now it requires a pre-exec stanza to do
stuff it used to do at startup. Your modified file in /etc will not
include this new stanza and your daemon is broken.

(And yes, this could be handled easily with a modified ucf, but
currently it is not the case.)
