I don't think that's really the same. The repackaging of Wii U games was because the Switch's install base was several times larger than the Wii U's, so they could sell them to people who had never played them before. The "Switch 2 Edition" updates are a way to try to extract some extra money from people who already played the games, but they're not going to fulfill the same strategic goals as, say, Mario Kart 8 DX, partly because they aren't going to sell as much, and partly because most of the people who buy them will already own the game and therefore only pay the upgrade price. I think from a strategic standpoint they're basically filler.
