Someone has perhaps mentioned this but it seems that 3rd function and hydraulic SSQA go hand in hand. Most implements don't require 3rd function so the the hoses stay "quick connected" to the SSQA. Then, when a grapple, for example, is attached and the SSQA is "engaged" the two hoses are then switched to the grapple, right? Removing the grapple then moves the hoses to the SSQA.
I can see the economy of the electric actuated SSQA but if you're going to have the 3rd function why not make use of it on the SSQA clamping? It gives you a clean place to store the hoses and quick couplers when not using the 3rdF, right? The hoses have to be handled regardless when mounting and dismounting a 3rdF attachment.
