/boot/efi/EFI/boot/ is writable as sudo

STORY:
Ran for i in `find /`;do sudo touch $i/moo.txt; done to touch a file across the whole system then ran sudo find / -name \moo.txt to find where it could modify/create files

STEPS:
1. install current core
2. for i in `find /`;do sudo touch $i/moo.txt; done
3. sudo find / -name \moo.txt

EXPECTED:
I didn't expect /boot/efi/EFI to be writable

ACTUAL:
It is writable which means there is the potential to make the system nonbootable on efi systems.
