Not really no. At the time i made these i had updated some of the "net" based software and i linked to the 2021 certificates dpkg. You are free to install all the dev tools and rebuild whatever you'd like on your personal machine though if you want it more up to date. Everything i updated on 12.04 was compiled on 12.04.Do you have a GitHub for the changes, and a list of what needs to be compiled for security update backports?
Cheers
