update-manager 1:18.04.11 (Accepted)

I saw this upload to bionic today and a similar one for a different
package yesterday and had some questions about it.

Why is it necessary to modify individual packages so that GNOME
Software won't uninstall them?

Is update-manager being a dependency of ubuntu-desktop not enough to
prevent it from being uninstalled?

If it is necessary to modify every package which a metapackage depends
on how is this work being tracked?

What checks are in place to ensure that no packages are missed and that
new additions get appropriately changed?
