Well I guess now it's time for Duncan's usual "stable or not" talk

Sure, I know,... zfs-fuse (i.e. the fuse and not the kernel module
version) is AFAIC, unmaintained (or soon to be).

No worries.
As I've said,... you probably should have some deeper discussions with
the core developers on how they think variable chunk size support and
any reshaping should be implemented.
Otherwise you may just put a lot of effort into something, that may
conflict some other longer term design ideas.

Cheers,
Chris.
