Do you mean that the GetCoverage result output is rotated for 4326?
That is exagerated IMO.

Do they have any client or test suite? Which one? Or it was never
really tested? What clients are people usually using with GeoServer?

I was wrong, GeoServer gives result smaller by 1 pixel if bbox is
defined  by "pixel" centers (grid points), so I have to use bbox
extended by 1 pixel, the same like WMS 1.3 which is not what WCS 1.1
requires AFAIK.
