Comment 36 for bug 1498059

To test this I enabled proposed on a Trusty system with the vivid HWE stack installed, and installed python3-update-manager, update-manager-core, and update-manager. I also installed libgl1-mesa-glx-lts-vivid:i386 and libglapi-mesa-lts-vivid:i386 to test the multiarch issue we encountered. Running hwe-support-status --show-all-unsupported I did see i386 packages listed and --show-replacements showed i386 packages. Additionally, libwayland-egl1-mesa-lts-xenial was listed as a replacement package.

I then installed the -proposed version of update-notifier and update-notifier-common and when I ssh'ed to my system I received a warning about my HWE stack being out of date. Subsequently, I think this is verified.
