I almost exclusively have used my Switch as a console and only had it undocked to play Animal Crossing. Now I’ve sold AC:NH I’ve no use for the handheld aspect of it. I’d absolutely buy a home Nintendo console if they made one, as I’ve bought every other Nintendo home console since SNES (ok, I didn’t buy them all, I was a kid, but I’ve wanted and had them all since then and started buying my own from the WiiU era).
As an aside, if they did this and released a handheld console also, I would likely also buy that, although honestly I am not missing having a handheld console in my life.
