Yes, but how do you know this is the label you wanted?  Consider the
case where there's more than one pool with this name.

Then I wouldn't use /dev/zfs.  The less stable and standard is the ZFS
API GRUB uses, the more likely is that one can argue it doesn't fall
under the "system library" exception.

Directly accessing on-disk structures is entirely different, since a
data structure itself can't be copyrighted.

I agree.  But I'm still concerned about the technical problems.
