  That's how it works.  It's an enabled module.

  2.x didn't do that, because it had no "mods-enabled" directory.  It
loaded all of the modules which were used.

  Adding a mods-enabled directory solved some problems with the way that
v2 did it.  But... at the cost of other side effects.

  Hmm... that's what virtual servers are for, right?

  It's expected.
