Won't anyone think of the giant multinational corporations instead of the kids learning to program for once.
This is a game console, not a PC. Developing games, for better or worse, whether it should be this way or not, is an extreme privilege. Sony basically never allows individual developers to register in any capacity. Xbox does, but if you want to actually publish a game, you're going to be in for a hard time.
Kids have programmed games for their calculators. This is like “throw it together to show off your friends,” it doesn’t need to meet Nintendo’s UI standards.
In that case, unless it goes on the eShop (thus meeting Nintendo's standards), every single one of her friends will also need a devkit to be able to run it; as retail units can't decrypt devkit-encrypted games, nor vice versa.
Might as well get a Steam Deck before convincing Nintendo to send over 10 devkits for children.
Game consoles are arbitrarily restricted PCs.
It's not a binary choice. Kids can learn to program in 1000 different ways. Getting social Brownie points for pointing out someone else isn't being incredibly generous is pretty poor behaviour, I think.
The biggest motivation is to show-off your creation and if all your friends play on the Switch and your game isn't there, it might as well not exist at all.
I learned programming on a Commodore 64, because I wanted to make my own games. Back at that time the playing field was fairly level as evidenced by the fact that a couple of the prominent game developers were almost kids themselves.
