geli and soft-updates

[Vinny]

Hi,

I'm wondering if soft-updates on UFS2 should be enabled
on a geli provided disk, da1.eli, for example.  That is,
should I use -U:

newfs -U /dev/da1.eli

or not use -U?

newfs /dev/da1.eli

Will -U help with crash corruption protection on a geli
provider?  Does my question make sense?

Thanks for your experiences/expertise.
Vinny

P.S. Anyone running ZFS on multiple geli providers?
