It worked out for Notch, sure, but most indie devs don't get the luxury of only considering console ports after they're already set for life from initially only releasing on PC. Planning for cross-platform from the start is table stakes, especially now the Switch has become just as if not more of a popular platform for indie games than PC is.

Most indie devs already strike gold if they manage one platform at all.

Too much is wasted on what language, or engine to use, instead of what actually make as a game.

And even when everything is done right, it is a drop in the ocean of daily released titles.
