I wouldn't call it obsolete. If you have console with firmware <4.0 you need to turn of gamecart port if you update. So no playing original carts anymore
I have the same ReiNX. I'm a bit affraid to try it without this option. First post shows version with this option but version 1.0.0 and 1.0.1 doesn't show it.
I have really strange issue. I folowed the guide, inserted payload (reinx.bin), and I see boot logo from reinx, then there is Nintendo Switch logo and .... black screen. I made backup nand and boot with hekate.
My Switch is 2.3.0. Could it be microsd card? (fat32 formated)
if they get permission from 4j (the studio who helped put minecraft on consoles), they could put the console edition tutorial worlds in the game, as seeds
and i mean all of them (if not, maybe a few highlights, like TU1, TU31, and TU69)
