That's not how I understand the documentation:

Virtual accounts use the NT SERVICE domain, but managed accounts 
seem to be subsumed under your normal AD domain name.

Apart from the fact that NULL is a terrible password, I'd still be more
comfortable to allow a NULL password as a user defined option on the
command line.  If not -W NULL, what about '-w -' or a long-only option
like --null-pwd?
