Yes, but what if I overwrite the device with random data from the very
first to the very last byte? Suppose the size of the device hasn't
decreased I'd think that wear-levelling has no chance to spare blocks in
this case.

In any case, provided you take a factory-new drive and immediately
install an encrypted filesystem on it, any such "orphan" data would be
essentially random.
