If this were just in the probe path (which it is today) I would not bother with the risk for a 3msec potential saving. However, you are going to reuse it in runtime resume where the effects will be more obvious. Hence applied to the togreg branch of iio.git and pushed out as testing. *fingers crossed* no one has out of spec wiring that needs a little longer than the spec says.
