Hah - I was going to mention all the other types of things the fire people seem to be blocking, but decided to stay focused. But yeah, it seemed like 'aversion to change'. "Firefighters might trip over solar panels on balconies" or something kind of far-fetched sounding.
This is funny. You might notice that I write insanely-long comments because these types of things pop into my head every time on HN (better get ahead of it because people will pick apart my quick comment if I don't cover as many bases as possible in the original comment!). Your method is better! I have to learn how to be more "focused" and let folks just do their thing and then reply succinctly like you did here.
Good plan.
