Yep, that would work, but it forces changes to existing installations
(users need to update the passwd file) and all special applications 
need to be updated at once. That's major, compared to the few 2003 sites.
(having 2 entries in passwd doesn't really help).

The solution I proposed in the other e-mail allows a gradual migration,
application by application. Once it is is place and all special applications
use it, we can then change mkpasswd to have the root/uid=0 entry (which
is an excellent idea).

Special applications would work with old and new style /etc/passwd 
formats and everything would be transparent to end users. Only a few
porters have to redefine the macro ROOT_UID. 
I could code the new cygwin_internal value this weekend, so that it
goes out quickly.
