With how the Evolution Plan was meant to be at the beginning in comparison of now, one could argue they’ve always been flexible to shift and change their minds. And how much they’ve stuck to things in turn.
I wouldn’t take the map seriously in what goes where. Hell, not everything in that LEGEND is represented on the map. And that I imagine they’d only have the concepts of what to do next, and not necessarily the how.
Ryan Theme Park shows this well, especially in how much has shifted since even the residential plan.
