The build finished, and I installed Ubuntu, Pop, and GNOME sessions side-by-side. All three worked, and the GDM theme changed based on the alternative selected. I believe the second patch version works as expected.

Take, for instance, pop-session, that installs /usr/share/gnome-shell/theme/pop.css and /usr/share /gnome-shell/modes/pop.json In order to supply a custom GDM3 theme, which is currently hardcoded, the ubuntu.css file must be replaced with this pop.css file. This breaks ubuntu-session, causing it to have a different shell theme than expected. What would be desirable is for the GDM3 CSS file to be hardcoded to gdm.css, which would be a symlink to the correct stylesheet for the flavor. This would allow multiple GNOME Shell sessions to be installed at the same time.
