    I guess these features are in the mass-testing long enough and did
    not cause known grief, so enabling should be okay - at a risk of
    being the first "strange" configuration where things don't work ;)

    Possibly, the main drawback would be the loss of compatibility with
    proprietary Solaris ZFS, i.e. you won't be able to import the pool
    with an Oracle Solaris installation. If that does not matter to
    you - go ahead... and do have backups prepared, as always ;)
