Didn't NetBSD work this way at one time ? I have a 1.6.2 server configured
with /28 on the primary IP and /32 for aliases (all in the /28 subnet) on
the same interface. I clearly remember that using /28 for the primary IP and
aliases didn't work (I don't remember the exact behavior though).
Something probably changed in this area since 1.6.x
