Perhaps but...that point is academic. Because such contracts were never formulated PRIMARILY BECAUSE OF THE ZONING RULES YOU WANT TO BROADEN, We are left with a real live issue of whether to extend of limit the arbitrary power of politicians (at the federal level?) over a specific piece of land.
Say what? I never advocated zoning over covenants. Thats a weak strawman argument, if ever I heard one.
We are stuck with what we are stuck with; primarily zoning boards and their non-democratic/non-representative decision making. If the choice is betweeen zoning boards and NOTHING, then I'll take the former with one caveat; we better make damn sure they make decisions that reflect the will of the people they represent.
BTW, if you really were a member of the real world you would recognize that the people allowing this mosque to be built are the same ones that wont let the Towers be rebuilt and the Greek Orthodox Church be rebuilt. Since we're not about to get rid of Zoning, its time to make them live out their charter.
