I find it interesting because often the best way to achieve a safe building code is to learn by allowing with basic guard rails and iterating as things happen. This isn’t ideal for the rare individual impacted by the “things happening,” but collectively we refine and iterate. Our current standards weren’t arrived at by navel gazing - we got the codes we have by experience. It’s hard to realize that from the present that you can’t reasonably learn without doing and by constraining without learning prevents growth and learning.
Are there lessons on safety that need to be learned here? We already know what the happy path looks like, and we've plenty of lessons on what the unhappy path will look like.
It isn't as if electric charge coming from balcony solar panels is some new magical-seeming type of electricity.
"Things happen" is a interesting way to say "houses burn down and kill everyone inside". And I don't believe that electrical standards were developed with the idea that houses could both consume and generate electricity.
Not to mention that most houses aren't up to current electrical standards, much less fire codes.
