Fair point. I just got over excited 🙂
Really old digital version may only be 16 bit, or (relatively) low sample rates compared to what is used today, especially if made before the 1990s. These are quite possibly going to be inferior and at the least limit the options for further processing.
Of course it's a moot point if we don't have the original analogue recording to compare the digital version to!
There was also my original point that in the future we may be able to recover more from analogue tapes than we can at present.
