I definitely agree with this point.
Is there any solution, except from building your own kernel, to the
scenario I described?
I think there should be.
(I've personally run into this with VirtualBox, which I IIRC couldn't
load, even though I provisioned my own PK, and signed both kernel and
VirtualBox module with my own key. I could've compiled my own kernel
with my //own key, but that is pretty impractical for most users.)
