Why would devs back another underpowered Nintendo console?

They wont. Most of them, like Fromsoftware and Bethesda are only gonna port old games to the console, so strictly speaking Nintendo can claim they have their support, even tho they are only going to port old game or make some shitty spinoff like Squareenix does

There would be a certain appeal of farming out some IPs to companies like From Software and Bethesda for mature IPs like Metroid, Eternal Darkness or something else like that.
