Dunno. I did not file the bug. I just know it's not in Lintian. :)

Is the bit required? With a view toward security, it seems
disadvantageous to grant execution privileges to files not intended to
run in Debian. I checked both the UEFI [1] and the systemd boot [2]
specs, but found nothing about the executable bit. I planned to unset
the bit locally until I realized my GRUB2 boot sequence may not use
those files.

Kind regards,
Felix
