I have seen some pretty weird issues and have work in process to have a bit more fool proof approach, but I haven't had time yet to finalize it properly.

Yep, UFS+GPT works fine here.

Just for archieves: errors for ZFS + GPT

UEFI is not available at the motherboard.

It also may have to do about what other devices are there. And also if the system has plain BIOS or BIOS emulated on UEFI.
