Those are the image libraries and libxml2.  And, of course, any
prerequisite packages needed to build those: zlib, libintl, libiconv,
and the libraries, like libnettle, that GnuTLS depends on.

Security is not just about secure communications.  I'm sure you know
that.

It is empty because it doesn't lead to any action.  We've been talking
about this for months already.

The actual discussions were private, not on any public list.

I think it's well beyond our capacities and resources, yes.
