Most quest authors are more interested in pushing the envelope rather than doing a straight-forward Zelda 1 adventure. Many of the new features are intended to cater to that.

I think before any new features in the spirit of Zelda 1 are added, the classic features need to be tightened up. Restoring backwards functionality and improving the faithfulness to the original NES game are just as important as finishing up the new features in 2.11.
