> A lot of people don’t care about fire safety either (until their house is burning down) which is why we have regulations, building codes, mandatory sprinklers in offices, etc.

We don't have mandatory sprinklers in home offices and undeveloped land and buildings that are still under construction.

The problem with the equivalent distinction in software is that there is no clear point that software is "finished" like a building is. The architect doesn't come back and make changes a year after the occupants move into a building.

If there is no exception for new code still under testing then there is no way to test new code. But if there is, everyone will live their lives inside of it.
