This is because systemd only really looks at the foo.wants/bar.service
symlink itself -- it's actually okay for that to point into
nothingness. I think this is mostly due to the fact that the actual
units can be in /etc, /usr, or /run, and even move between those.
For example, you might have
/usr/lib/systemd/system/multi-user.target.wants/foo.service → ../foo.service
and then override this with
Then multi-user.target will still use the unit from /etc, *not* the
one from /usr, even though that's where the symlink points to. In
this case this is pretty obviously the correct behaviour; in your case
it's admittedly confusing.
I'm not entirely sure if dangling symlinks should be counted as
"enabled", but this should least explain your observation.
