Yeah, that's what what I decided to do. Thanks.

This seems to be more of a query for debian-devel, to be honest.
Two packages do not seem particularly useful to me. Since apt depends
on libgnutls30, I don't see how an OpenSSL backend for qpdf could
minimize installation size. This suggests to me that you should stick
with GNUTLS for Debian.
