Yes, I'd appreciate grub.

When debugging the boot process with an encrypted rootfs on my Odroid
XU4s I found it very comfortable to be able to easily switch between
boot configurations with grub (which I had thanks to sesse's install
script for XU4). And maybe it's not just me, because one of the usage
scenarios for SBCs will be self-hosted services (think of freedombox),
for which disk encryption can be an issue.
