No doubt all true, but in real life I don't see a problem. If you're
shooting wide open then you by definition are most likely looking to
shorten the depth of field (speed's rarely an issue with apertures in
mind--at least for working photographers within my experience--it has a lot
to do with what happens in the lab, but that's something else) and so your
subject isn't likely to be on the periphery of your view area, and if
you're stopped down then it's likely the increased DOF will take care of
these details whether you can seem them clearly or not. For all intents and
purposes I just don't see an issue. Tests are one thing, work out in the
field another. Now I use your data (well, I peruse it, and thank you very
much) to draw pictures in my mind of gear I might never lay my hands on,
probably will never lay hands on with the big stuff in mind, but I can't
bring myself to believe that any bench work could ever be truly indicative
of how camera gear behaves "out there." When I go to shoot I think a whole
lot more about the film I'm taking vis-a-vis the light I expect to have and
whether my subject will be moving or still than I do about my lenses at
all, and peripheral field of view is something I've never given a serious
thought for quarter of a century.
We're strapping the butterfly to the wheel here, gentleman.

The "vignetting" grades on my lens test page are a predictor of this.
The SQF grade wide open in the corners will also tell you how useful the
lens is for focusing in the corners. At C- to C+, I never found my 35mm
f/2.8 SC to be very useful at corner focusing.
