That is a regression, afaics.  The privileged account needs the specific
user privileges to change the user context, but if it has these
privileges, it should behave not different than when running under the
SYSTEM account in earlier versions of Windows.  The old ftpd doesn't test
the uid for being any fixed value.  Same for inetd.

Uh, no.  the old rshd has this in the code:

  #ifdef __CYGWIN__
	  uid_t ROOT_UID = getuid ();
  #else
	  ROOT_UID	(0)
  #endif
