If you can't continue to provide and maintain the v1 API backend because its approach and assumptions were chosen badly, that's also a way to fail. HN is full

If you can't continue to provide and maintain the v1 API backend because its approach and assumptions were chosen badly, that's also a way to fail. HN is full of 100% black or 100% white theses that are the equivalent of guerning youtuber clickbait. Most of it is true under some conditions and false under others... it would be better to put it that "Sometimes you have to pick if v1 or v2 of your api is more likely to kill your project".
