This is our key disagreement, I think.  As far as I'm concerned, this is NOT
"static" information: it *does* change.  In general, it only changes once, but
it is this one change that makes or breaks a gas gauge.  (It could even in
theory change multiple times, but this is definitely a corner case, I admit).

As long as I was receiving notifications, I would not, as a monitoring
application, do any polling at all.  I would only poll if I hadn't heard
anything for a while.
