What the Hell is a "esoteric value"? How does one measure "esoteric
values"? Is there a "esoteric value" meter?

Sure. It's called an E-Meter and your local Scientology Centre has them.

One parameter that might be considered esoteric, is delectric absorbtion.
This will affect capacitance, but can be measured out. it can
affect DC circuits, or ac circuits with a dc bias. Better caps have low DA.
Electrolytics are really bad in this respect. DA also causes frequency
dependant cap values.

DA hasn't been shown to be non-linear though and it's a very small effect with most caps.

With electrolytics used as coupling caps you can effectively avoid the issue by using large
values.
