Not sure if I have point, it's an argument at least.
That the guix binary is a bit of target for the classical problems
involved. And who knowns, maybe one can find a K&R "hello world" string
in a binary as the best and worst of it.

But this is inherently ugly, to see the measures and crud involved, with
awareness of developers that it touch upon sensitive subsystems.
And may very well make it more accessible for study, publications and
discussions if just shafted and most likely fale positives with academic
print og preprint review.
