The stuff in your first paragraph is already being taken care of outside of the forced dropback. The forced dropback is not their to solely fix those issues; it's there for realism.
You're looking at the dropback as the solution and it is not being used solely for that purpose. DE sheding blocks and accuracy hits for certain passes is getting fixed regardless; doesn't mean you do-away with the forced dropback.
I hate to imagine how ugly the dropbacks would be if users were responsible for doing them on their own.
