I think PC needs to rewrite Wailord’s size in the dex by now

It just can't be the Gigantic Ruler of the Sea we all knew anymore, can it? Every main game, it never appears in its true dex size, which I can understand that in the 3ds titles due to it possibly swallowing the whole battlefield, but even Dondozo didn't appear in its full size in the wild in SV. Why did they give these pokemon sizes the games can't handle in the first place? It's pointless
