The OS can do it, and some Nintendo titles on the Switch do use this capability, but I have talked to Nintendo directly about using it, and it's a hard No. I can't even use the JIT feature purely for dev.

Really? What is the justification for allowing Nintendo titles to use it but not third parties? Security concerns?

That's what they claim, but ultimately it's their thing, so they do with it whatever they like.
