Is that something you need in /boot?
Yes, because content is directly installed there.
And journaling actually is more a problem than a solution due to
firmware (or grub) filesystem drivers often not having full support for
the journal. Luckily this is rarely a problem in practice because /boot
is rarely written to.
We could just make those read-only from the bootloader side then. I
have /boot on btrfs, which grub/efifs doesn't support writing to at
all anyway. Write grubenv settings into the BIOS boot partition or ESP
rather than /boot.
