Hi Aaron,
On our team backlog[1], you added[2] the item: * Setup.php speed improvements and service registry
Tim and I saw this when we were making our prioritization pass, and didn't know what to make of it, though we're trusting it's a pretty important idea coming from you. What did you have in mind?
Rob
