BiCon was actually requested some time ago,
https://bugs.debian.org/446813, but no one has packaged it yet.

If you want it packaged, you can package it yourself and become the
maintainer.  Start by reading the New Maintainer's Guide
https://www.debian.org/doc/devel-manuals#maint-guide.  Ask questions on
the debian-mentors mailing list or on #debian-mentors on irc and read
the Mentors FAQ https://wiki.debian.org/DebianMentorsFaq.  Then request
sponsorship when you are ready to have someone review it.
