It is actionable in the sense that you can now unplug the computer, which was the use case reported by the people who miss having the charge percentage constantly visible in the system tray. If it's too annoying it can be turned off, though that's not very discoverable. Of course this works both ways, the people who do want it can turn it on, which is what we have now.
If complaints pile up, maybe I have to revisit the applet visibility condition change. Hard to tell which side is in the majority because obviously the people who liked the change won't complain.
