Shrinking the vdevs requires moving data. Once you move data, you've

IMHO ability to shrink/grow pools even if restricted so no snapshots
and clones can be present in a pool during shrinking/growing would
still be a great feature.
FYI, we're working on being able to shrink pools with no restrictions.
Unfortunately I don't have an ETA for you on this, though.
And as I'm sure you know, you can always grow pools :-)
