Ah, a smart squonker in a round about way of seeing it. I rather keep it human deciding the juice flow. Sure, it might sound and even appear nice for the nonce, mark me though it'll start overfilling or under-filling. Then, you need to get into fixing it if you can. Nope, not a monkey or circus I want.
I don't drown my deck in juice at any given. Yes, my wick stays wet cotton or rayon. That doesn't infer a soggy deck. It means about every dozen or so hits I give a gentle squonk, maybe two and let the juice suck back down. The juice saturates the wick, then goes back to bottle for later use. So, I'm not adverse to the extra step of actually squonking. It really doesn't seem a chore or work.
I can agree with you that it seems to have potential. Will even admit that before looking at your posting above, I had thought on it as a possible buy. Your explanation talked me out of thinking like that.
If it was made more toward the specs you posted, might be worth a version 2 buy. If not, I'm not sure it would be for me.
