it's a shame they don't want folks to use Discover. I'm sure it'd be great and not cause issues, and one could always go back to pacman if there ever was an issue...
There isn't a packagekit back end for Arch based distros so it doesn't work.
Yes it does, I've regularly updated my system that way. It is a bit buggy at times though, I ended up uninstalling the backend.
But it's still useful for managing Flatpaks and stuff.
Yeah, I thought it was only usable for flatpaks
There is, but it is not great at handling conflicts, and other yes/no questions pacman might ask. This can lead to something going wrong during installation or updates.
I don't have any knowledge why you should or shouldn't, but it seems like you could have it if it was just pulling from flatpak sources like flathub.
