I agree we need non-root passthrough.
Could we restore what we previously had, but fence it off with a module
parameter to opt-in to allow it? Like setting a silicon chicken bit, and
taint the kernel if that helps convey the responsibility taken with such
a parameter?
The only other possibility I can think of is start a command allow-list
specific to non-root users, along with your earlier patch's decoder.
