According to the new WCA-Terms work, those are resource manifestations.
Even under the current web they have the same "identity" because they were
retrieved with the same URL.

Yes. Two things with the same URL must certainly share a UUID no matter
how textually different they are. The logical object behind them is the
same. Without that much of a guarantee we can have no useful concept of
identity at all.
