Serves me right for idle *and* public reflections... :,)

No, only the winsock2 one is necessary.

Yes, winsock starts correctly (i.e., WSAStartup() succeeds) even with no
access to these keys.

Here is a table that summarizes my findings:

winsock  winsock2  WSAStartup  notes
=======  ========  ==========  =====
yes      yes       succeeds    exim: starts up
no       yes       succeeds    exim: IPv4 socket creation failed
yes      no        fails       exim: cannot find smtp/tcp service
no       no        fails       exim: cannot find smtp/tcp service
no       no        succeeds    strace exim: IPv4 socket creation failed

Sorry, I don't.
