The removal of the whole code seems fine to me and from my small testing, it seems you didn't forget to remove anything in the package.
I have a small dummy question though, debian/rules were already using dh --with python2 and you still use the same, even if you ship a python3 package? (python3-update-manager). Do you know what's the plan for that?
Apart from that all, looks good. I'll let gary looking at the update-release-manager side :)
