I don't know that this is true.  Different people hold different
opinions about this.  Clearly Debian has made a statement that they do
not consider OpenSSL part of the OS, but there are other cases that
are not as clear cut.  My point is not to argue whether OpenSSL can be
part of the OS or not.  My point is that I don't think we in the GPG
world get a vote on this: it's not our OS and so not our decision to

I'd think that makes it easier (at least on the context of GPG).  The
GPG keyserver code doesn't do anything strange or unusual with its SSL
support, and so will work equally well with OpenSSL or GnuTLS.  All
the SSL functionality is hidden behind the libcurl API.
