And those who are unfamiliar with a system will likely use the default
filesystem an OS provides.  That's UFS2 for most people.

Especially since ZFS is still considered experimental, I find it
unreasonable to have the installer support something that isn't
considered permanent.

Also, since ZFS is a hog when it comes to system resources, works best
on amd64, and many other factors/tuning, you expect this all to be
available if someone wants to install to an embedded firewall?  Or to
some little special purpose system?

I don't use ZFS, UFS2 works fine for me.  I would find it ridiculous
to see ZFS support in the installer, but all GEOM should be supported.
 Especially the raid3 and mirror.

I think you're expecting the world...  Maybe a check is in order.
