What would less than 4GB RAM have meant for the Switch?

I doubt it would have a major effect on sales if the Switch had missed out on "impossible ports" like Witcher 3 due to RAM limitations, but it may have had a minor effect in so much as it would've made the system seem less viable to the probably small but still significant portion of buyers who care about AAA games.

On another note, looking at what was accomplished on Wii U's 1GB of RAM in games like Xenoblade Chronicles X and BOTW, I feel like Switch exclusives so far don't seem to be maximising what can be done with 3.25 times more.
