Disagree with op for the bolded, its clearly outright the same iconic
cano universe referenced that appears in each Mario game up till that point and the same Mario we know appears in each prior game according to WOG stating both so....pretty much debunked.
The Smash Bros. series actually shows that the respective game universes in the game
aren't of the same canon anyway due to numerous trophy descriptions outright distinguishing that along with obvious lore discrepencies from everything to character heights and etc.Olimar and Kirby being both similar heights and similar to normal human's heights, need I say more?
