I have another idea, why the latest games on Switch (like Bayonetta 3, Pokémon Scarlet/Violet) performed worse than games in the earlier days of the console or games have a lack of content (like Mario Strikers or Switch Sports).
Nintendo wanted to release a more powerful mid-gen upgrade in 2021. This wasn't possible due to semiconductor shortages. They saw how Sony and Microsoft struggled and decided to release a new model, but only with a better screen (Switch OLED).
Since the release of Switch OLED we saw a couple of games which performed rather bad, similar how games performed on PS4 after the release of PS4 Pro. I assume that developers made their games with the rumored Switch 4K dev kit. All the games we saw during the last 18 months are probably made for a more powerful Switch model and are down ported for the regular model.
Some games, like a new 3D Mario, are probably delayed and should have been released last year to push the new hardware. And other games like Mario Strikers or Pokémon Scarlet/Violet were clearly released before they were finished. I guess the software output on Switch is a complete mess since the release of Switch OLED.
This is just speculation, but it makes somehow sense, I think. Maybe Nintendo releases the more powerful mid-gen upgrade together with Zelda in May. Switch Lite and Switch OLED were announced 2 or 3 months before release, so there's still enough time left.
