What is it depending on for the target?  Is the shadow-utils or something now
required?  That doesn't seem to make sense to me -- other then we need a
passwd/group/shadow/gshadow file to work with.  As long as something can provide
those, we should be ok.

Yup, definitely a bug and should be fixed.  native and cross cases should not do
anything with useradd.
