My point is that there is no longer an internal winbind in any
supported version of samba, only winbindd, the long-standing codebase
currently under source3/

The server services parser accepts either name and treats them
identically.

In terms of -dns, my point is that this configuration, turning on or
off the DNS server, is the only reason that an administrator should
ever need to deal with 'server services'.  The defaults work just fine
otherwise.  

The original plan for the parameter was never to have the full list of
default services exposed, just to list the changes (eg -dns for no DNS
server).  Had that been better implemented, we wouldn't be having this
discussion, it just would have remained under the hood.
