Wonders and holy sites should function as commons quarters

Unless forced to, I tend to build wonders in the most distant places possible so I don't end up crushing a tile with good yields or potential for a useful commons quarter. Not only would making wonders and holysites function as commons quarters give these rare districts more purpose and weight but it would also make cities feel more organic, it makes little sense to have the Eiffel tower or Empire State Building in the middle of nowhere, these should be in the hearts of cities.
