Some people talk about Reversible Decisions, and I think what you're saying plays into that sentiment.
Unfortunately some people don't realize that in many situations not making a decision is itself a decision, and so they don't always notice it when it happens. That can be anything from the ones you mentioned, like testing and tools, to authentication, auditing, localization, robust error handling, resource/memory leaks, or monolithic designs that prevent scaling.
