The /etc/systemd/system/default.target symlink is something the admin
is supposed to configure on the local
system. /usr/lib/systemd/system/default.target is the vendor default,
that is picked by the image builder and is in effect if the
/etc/systemd/system/default.target symlink does not exist.

hence, if you are an os developer who puts out an OS image you
configure the one in /usr/lib and do not supply the one in /etc. If
you are an admin you set and change the one in /etc, and can revert to
vendor defaults by deleting it.
