I don't know about ramifications (though I suspect that a broadening
error scope would decrease ZFS' ability to isolate and work around
problematic regions on the media), but one thing I do know. If you use
FreeBSD disk encryption below ZFS, then you won't be able able to import
your pools to another implementation -- you will be stuck with FreeBSD.
Btw, if you want a commercially supported and maintained product, have
you looked at NexentaStor? Regardless of what happens with OpenSolaris,
we aren't going anywhere. (Full disclosure: I'm a Nexenta Systems
employee. :-)
