ZFS root on single SSD?

So, I've been running ZFS root mirror across 2 spinning disks, and I'm
upgrading my home server/nas and planning on running root on a spare SSD.
However, I'm unsure if it'd be better to run UFS as a single drive root
instead of ZFS, although I do love all of the ZFS features (snapshots, COW,
scrubbing, etc) and would still like to keep that for my root drive, even
if I'm not mirroring at all. I do notice that FreeBSD has TRIM support for
ZFS (see http://open-zfs.org/wiki/Features#TRIM_Support).

So is there a good reason NOT to run ZFS root on a single drive SSD?
