A related issue. It is probably more of a generic ZFS code base thing,
but what do you think?

It would be a nice idea to be able to _prevent_ ZFS pool from groving
automatically. This could be a flag in the pool label or anything. This
is not a real issue in FreeBSD at least for me because it is in any case
better to use glabel to label partitions so that the names don't change
between reboots when devices are added and removed.

But with pool using whole disks this would be useful if one wants to
keep pool at certain size eg. to be able to temporarily use larger disks
and later move back to original-size disks.
