Comment 27 for bug 1616650

No, there is a much better (albeit not perfect) solution: enable experimental.refresh-app-awareness, so automatic refreshes will be held for a maximum of 7 days. So closing chromium (or any other affected snap) and applying updates is needed only once a week.

Hopefully this will become configurable, or a notification system will be implemented for snaps to alert the user that a restart is needed.
