So, sessioninstaller is an aptdaemon based implementation of the
PackageKit session interface. The two can be dropped together, since
they are both unmaintained and not needed. PackageKit provides
everything needed as a replacement.

The dependency by gnome-software is illusory, as it depends on
PackageKit D-Bus interfaces (provided by PackageKit). The dependency
wasn't even present in xenial, as far as I recall...

oem-config-gtk is a single script[1] with only a few lines of code
actually using aptdaemon, and that can be ported to use PackageKit
instead.

language-selector-gnome is similar[2], and should be easy to port out
to PackageKit, assuming this is even needed anymore. It doesn't look
like it's maintained either...
