Proposal for reducing the number of unremovable apps in GNOME Software

[mcatanzaro gnome org]

Hi,

Currently about half of the GNOME core apps are unremovable in GNOME 
Software. It's the set of apps that are not new additions to core over 
the past two years, but at this point that's entirely arbitrary. So we 
need to find a better criterion for determining what should and should 
not be unremovable.

In the interests of allowing users to replace core apps with their 
preferred alternatives, I'd like to propose that only the most 
essential applications -- stuff that cannot plausibly be packaged as a 
properly-sandboxed flatpak -- should remain unremovable. Specifically, 
I propose that <mandatory_for_desktop>GNOME</mandatory_for_desktop> be 
removed from the appstream metainfo for all of our apps except the 
following four:

* gnome-screenshot
* gnome-software
* nautilus
* yelp

This matches one of Javier's proposed moduleset changes [1].

Thoughts?

Michael
