One major implication is datamining. Switch 2 exclusives were unusual for modern games in that there was genuinely no way to dump their files, study their code, etc. Which has its upsides: games could have actual hidden secrets for the first time in ages...
The thing that was significant about all the Switch homebrew stuff, both hacks and emulators, was that the Switch was affordable and also ran its own games like shit. The Switch 2 is medium expensive and fairly capable so on some level who cares.
