I think that would be my worry; I did wonder about trying the same with my own installation, but even if it were possible (or advisable for other reasons; I'm not sure it is in either case) I am worried that at some point something or other might want to use that last block with interesting consequences. I've just been having fun and games moving over to the gpart scheme and having to remember to include an extra block to keep the label information, since gmirror forbids me to add a labeled partition due to it being too small (in which case maybe ZFS doesn't use the full partition if it allows it to be re-added even though it's shrunk by a block)... but I'm going to rebuild my ZFS array from scratch.
