Thanks for the feeedback - I wanted to get this up and running as soon
as I could, so I just went with the method being used in PA now. Can you
please translate that into a time frame in dates? We should probably try
to figure out what API we want to ship as the on-by-default for the next
PA release (and if it's the Media API, turn it on in master asap to get
more testing and flush out any issues).
