My hot take: if corporations are going to insist that OSS software they use have things like mandatory two-person code reviews, SLAs, written succession plans, and so on, then the end result is going to be that corporations don't use anywhere near as much as OSS code as they do today.
Since that would be unpalatably expensive to corporations (that's why they're using this OSS today), this is corporate hot air plus yet another attempt to lean on OSS for even more unpaid labour.
