You still need the flight visibility specified in the approach, if you are
below DH/MDA, don't you?



Absolutely, and continuously until touching down.


Let's say the required vis is 2 miles. Reported weather is 3 miles, and
sure enough, you spot the field 3 miles away. By the time you're on 1/2
mile final, it starts to rain and the visibility goes down to 1 mile, but
you can still see the runway clearly. Are you really required to go missed
at that point?

Legally, yes. But, with high minimums like those you cite, most pilots
would land. The regulation is written with the typical minimums in
mind; i.e. 3/4 or 1 mile (and lower with ALS).
