It's not, but you can run 'mkfs' with flags that do the same thing. The
exact syntax is in the Solaris 2 FAQ.

Not really. SDS/SVM doesn't really make it any easier to move slices
around, and it's still impossible to shrink UFS filesystems.

So unless you setup the system with free space for things to grow into,
and the things you want to grow aren't boot critical, then it doesn't
help much.

I think "newer school" is to put all OS filesystems into one filesystem so
you never have to repartition....
