E airspace doesn't change the one-in , one-out situation. I don't think the airlines, who are the most affected by this,
(I may be wrong, but it would be easy to do a statistical survey), would go for the "IFR pick-up".
What procedural E airspace does, is introduce unnotified VFR aircraft, a minority, into the equation.
This is the real hazard.
