The hive mind is like that for a reason. Making it easy to do the right thing and wrong to do the wrong thing has massive effects, I'd argue the magnitude of which scale exponentially with the growth of an engineering team. Really really talented engineers make mistakes all the time. To the extent that we can systematically limit those with little to no downside we absolutely should, especially when it comes to security.
