Rumoredly, according to people who have read the leaked Nintendo documents (Modern Vintage Gamer has implied it in replies to comments on his videos), NVIDIA had found the bug with the recovery mode before the Switch's launch; but Nintendo couldn't just move the announced Switch launch date to wait for a chip revision, especially after the Wii U financial performance. So, off it went and they just had to cross fingers and hope nobody found it. Nintendo probably got a good discount for that mistake too.
