Should we simply disallow ZFS on FreeBSD/i386?

In Russian we have a good saying: "You can teach a bear to ride a
bicycle, but will it ever enjoy it?"
The same is here - seemingly due to the ZFS design limitations and
limitations of the FreeBSD kernel you can't get ZFS to run reliably out
of the box on i386. Yes, you can probably do some tweaks here and there,
to make it more of less stable given the workload, but that's not what
most of the FreeBSD users expect from the file system. Unlike you, most
of administrators won't even bother to read tweaking documentation
explaining why ZFS is so tricky in i386, let alone doing actual
trial-and-error to determine the right set of tunables. More likely at
the first incident they would just dismiss FreeBSD/ZFS as a crap.
