If there was a security bug found in Trac now, Dapper might’ve not get
updated. Pinning trac to Dapper doesn’t take care of tracking trac’s
(or any other universe package’s) security support by hand.

Yes, in case of the *current* fixes for *Trac*. It’s not an
universal approach for other packages and future fixes for Trac.

Great. I’m writing about the general approach to backporting universe
packages (for security fixes) and why simple pinning to current-stable+1
is not enough; trac was just an example of an universe package that’s
useful on servers.

What’s tricky in getting the orig, diff and dsc files?
They’re even linked from the source package’s page.

I don’t have upload rights and I’m not building the packages for general
use (in a clean chroot, with proper testing, etc.), so I doubt my builds
would be useful to anyone.
