I like the idea of getting rid of
the partition letter.

Is there an ioctl() to find out how
big a wedge is? I've never much liked
fetching the entire disk label, then
working out which entry based on the
pathname to the device. It's got a
precarious feel to it.

Similarly, is it possible to grow
a wedge with discontinuous space?
Let me explain that with an example.
I have a 100gb RAID and it all gets allocated.
The RAID supports growing the unit (logical disk)
by, say, another 100gb. I want to add the new
space to an existing file volume that
might not be on the end. OBTW, growing
and FFS volume really ain't so hard.
