and I do not really follow what you wrote in there.
I do have the feeling we draw different conclusions.

to clarify what I write:

import (creates new GIMP document window): bg-color-layer should be
set to png bKGD.

import (creates new layer): png bKGD should be merged with image pixels.

I cannot agree with this. completely different intent.
bg-color-layer and png bKGD are about what will the image consumers see.
Preferences->Display->Transparency is about how do GIMP users gauge
transparency.
