If I take a look at /boot/grub/grub.cfg I see the lines:

function recordfail {
  set recordfail=1
  # GRUB lacks write support for btrfs, so recordfail support is disabled.
}

So, I guess this is intentional, at least.

Are you booting via UEFI or BIOS?

I could at least reduced the timeout by setting GRUB_RECORDFAIL_TIMEOUT.
