The problem I was attempting to describe: all pool members must be the
same size, otherwise all members are considered to be equal to the size
of the smallest. In English: you cannot "mix-and-match" different sized
disks.

C'mon guys - that has nuthin to do with ZFS or any other RAID [1].
Grocery-store rithmetic says you can't put 2 liters of wine into a
one-liter bottle.
(though there IS a MIL-SPEC exercise called a 'blivet' that tries to get
ten liters of sh** into a one-liter container .. ...with predictable
mess to be dealt with, fecal matter having rather poor compression
algorithms)

[1] Though some 'grid farm' and cousins attack the problem differently -
sort of a JBOD confederation with (some of) the contents replicated one
or more times and in one or more places - wherever there is space, or
least-usage, or greatest 'quality', or most eager 'volunteer', or ....
Whole 'nuther subject, those.
And neither ZFS not HAMMER is of that family.
Not *yet*
