Then, rather than actually doing much client-side with this, we'd just show the formatted URL, and allow users to click on it before they do there thing. i.e. the diffing of the changelogs would be done server-side (if desired).

But that it something the gnome software backend could deal with,
i.e. follow the link in its own code and render it itself.

what does gnome software actually expect as delta? a frickin' text

So yeah, no problem, having a service for this in systemd sounds
totally OK. It's just a matter of someone implementing it ;-)

That'd be excellent.
