I this it's just ZFS that has that "limitation", LVM and Btrfs just let you mix drives of arbitrary sizes.

Everything raid has that limitation, including LVM, mdadm.

Btrfs has a more flexible block allocator but its parity implementation is still unreliable.

ZFS will also let you mix drives of different sizes. And the pool would grow as soon as you remove the smallest one.
