One weird thing, though: instead of being at the bottom of the
tank like you'd expect, the flapper sits a couple of inches up on
an extension. This is obviously by design. Seems strange to leave
that much water in the bottom of the tank; there must be some
reason for this. (Hydrodynamics?)

One possible benefit is that the cold fill water mixes with the
more tepid water reducing the likelihood of tank sweating.

Wow - I think you have hit the nail on the head. I am going to have
to see if I can modify one of our frequently used toilets to reduce
the summer sweating.

Oh, dear Gott: any civilization that devolves to the point of worrying
about its toilet tanks sweating is surely circling the drain like the
latter-day Roman Empire ...
