Ah, but without the Reaper upgrades, the quarians would have just "curb stomped" the geth anyway. The quarians did not agree to peace without the threat of total annihilation. There would have been no reason to stop the battle, and the Migrant Fleet would have just plowed through the geth, as they had intended. (Actually, if the upgrade had never existed in the first place, the quarians would have won on day one. What I'm referring to here is a scenario in which Legion didn't get his copy of the upgrade to upload to the geth in Priority: Rannoch.)

As for Shep losing touch with organic life, I'm not so sure that would happen. One reason is that he/she still has memories from life as an organic. Another is that Shep has a clear-cut plan for his/her control of the Reapers, which varies depending on moral alignment. Paragon Shepbinger wants to act as a galactic guardian, defending the people of the galaxy from anything that might cause them harm. Renegade Shepbinger wants to become a god-king. So, really, if your Shep is Renegade, Control might not be for you. In any case, Shepbinger is infinitely better for organics than the original Catalyst, who, as an AI, was never in touch with organic life in the first place.
