Honestly, when explaining new functionality like this, it would be
lovely to also give an example of the _why_, not just the what.

Ie, some concrete example of "this is useful to have the remoteproc
continue scanning wireless networks" or whatever.

I'm sure there's some actual use-case for this all, but neither the
pull request nor the individual commits seem to actually explain that
"why", only the "what".

I've pulled this, but hope that these kinds of issues can be explained
better.. I think a lot of people care more about "why" than some
implementation detail "what" cases.
