No, this dependency is not real:
individual applets can be built without libbusybox.

It's just that no one implemented and tested necessary magic
in makefiles to make it work.

One of the reasons for this is that in this usage case there will be
a lot of code duplication in the resulting binaries:
every frequently used function will be present in many binaries.
This does not happen with libbusybox build.

Because username completion is a form of tab completion:
you type a partial username and press <tab> key.
