Nintendo has come a very long way since WiiWare and the DSi shop. It might have been a slow burn, but Nintendo has definitely learned a thing or two about digital storefronts, as well as interacting with indie devs. All that work lead up to this point, where the Switch is kicking butt and indies are finding big success. Nintendo's Damon Baker acknowledged the hard work it took to get to this point, and also made sure to point out that Nintendo's work with indies is an important relationship moving forward.
“All of these things have been a work in progress to create an environment that’s much easier to navigate and it’s really been resonating with the indie community. ...It’s important to the company. This is a long-term play.”
