Has there been any progress on this front since 2015? There should be a way to communicate to the user the existence of optional runtime-only dependencies.
For example, I installed Gajim recently and it pulled in Gnome's keyring, which is completely unncessary for me, as I already use KeepassXC. The package manager should also have a way to query this information, because packages that were installed as optional dependencies should not have to be manually deleted when their reverse dependency is removed.
