With a natural recharge rate of ~0, stopping becomes permanent rather abruptly. So I’m not sure what you assume the benefit of such a stance is.

Not what's happening in my area, the 80% (70% in case of a drought) limit seems to work pretty well, and has been working well for a decade now.

Recharge rate isn’t consistent across different areas. It can be quite high if a river happens to be nearby, you’re next to a large park with zero use, etc.
