We have a delayed put on the edp panel power. So keeping it just around
the bits where we need it doesn't have perf downsides and imo makes it
clearer why we need it - we've had some good amounts of fun in the past
where functions assumed that the panel is on but not all callers ensured
that. We've pushed the edp panel power handling down the callstacks due
to that.
