The alternative is we have a "download" stage, which means we can't do
the blue "restart and update" action as it would download for a few
minutes, and then randomly reboot when you had just started doing
something else while you were waiting. The depsolve step is also
important; we only show updates that can actually be installed rather
than dnf which will install a subset of the true update list if there
are tree compose problems.

We only do the auto-refresh on wired or wifi connections. If you chose
to do the manual refresh button on mobile data that's up to the user.

Right, and that's a valid point; but until we have some kind of
platform / application split like atomic/xdg-app it's just not
achievable to download and install the applications at runtime. I'm
trying to do the best with the bits we have at the moment, and when
we've got a better platform story we can do something better.
