Multiple Data References per AFAttribute

I remember reading or hearing there are plans for multiple DR for an AFAttribute.  Can we hear any more on this?

Interested in how you see it working...having a primary DR, then secondary DRs use the output? e.g. PI Formula DR performs a calculation on elements, the output becomes the AFValue.  If a secondary DR exists the AFValue is used, (let's say a PI Point DR exists as a secondary DR) then the result of the Formula DR can be sent back to a PI tag.

On occasions we have needed to write custom AFSDK code to get non PI Point DR values into PI tags (for various reasons).
