It's available, but it's the 2nd largest GRUB module at ~100KiB. And
on BIOS we're space limit right now to 1 MiB MBR gap or BIOS Boot

GRUB works fine with a zstd compressed /boot/ but obviously there's
next to no benefit compared to the added complexity since the kernel
and initramfs are already compressed.

So if it's not difficult to exclude compression on /boot/ that's
probably preferred?
