OTOH, I guess that if our encouragement is successful then there would
be fewer httpd installations utilizing mostly-painless OpenSSL patches
from their OS vendor over the next few years.  That may be bad for
security overall.

bad for 2.3 alpha/beta testing

There's no ready answer to this, but I wonder:  How much of the
current conditional logic is required to support the OpenSSL in

fully patched RHEL 4
fully patched Solaris 10
(some other typical server platform that bundles OpenSSL)
