it's been a while but out of a GAAP and overflying a D. It was never a problem as I flew under the steps. But I definitely agree that e over d makes a lot of sense especially if everyone has a transponder so ATC can see the VFR to assist in traffic avoidance for the IFR.
I understand you suggest they are not needed as everyone must look out and see and avoid, but that fails from time to time. That is why advanced aircraft have warning systems as a fail-safe for pilot error. That is why TCAS exists and gear warning horns exist etc so a transponder adds a layer of protection for everyone. Bit like reversing cameras in cars, they are a great control when see and avoid fails to work from time to time.
