Agreed.

Both these are unfortunate restrictions. I can understand that
expanding a RAIDZ would be a fairly complex operation but it's
probably the most requested feature. I'm surprised that Sun don't
allow removing vdevs from a pool - it's orthogonal to adding a vdev to
a pool and (eg) HP AdvFS allows both.
