Thanks for re-sending. I'm happier that you're keeping some basic
functionality here. No real objections at this point.

I need to apply it for testing and take a closer look, but its on my
to-queue list. However, with an upcoming conference, as being a little
later in the cycle I can't promise it will make it for the 4.9 merge
window. But we'll see.

thanks!
