Rather than remove it, why not remove the executable bit?

20_memtest86+ Searches for /boot/memtest86+.bin and includes it as an
option on the GRUB 2 boot menu. There is currently no line option to
remove this entry from the menu. The display of memtest86+ can be
inhibited by removing the executable bit from this file and running sudo
update-grub.

And yes, I know you are a grub2 developer :-) I'm just curious why you
recommend removing the package rather than removing the executable bit.
