Immutable was introduced to prevent dangerous scenarios that weren't
accounted for in original design, etc. It solved your crash when you
rep;aced a thin-pool with an empty table.
immutable is staying for now. And as it turns out allowing error target
to override an immutable target was always held to be a logical/possible
future relaxation of the immutable constraint.
