I do actually work on quite low level code. My mistakes are neither millions of euros nor company ending scenario. Just a lot of complaints.

I am not advocating for move early and break things fast. Not at all.

But in my environment I find the need to find a reasonable compromise.

Compromise that can also be having a set of test suites that allow to test things and rollback.

I am the one advocating for "clean code is the one you never have to look at, because it works, not the one that looks nice in the editor".

I understand your point, I understand that we work in different environments, but I also think that a codebase is a living creature that, if left unchecked, will just explode in complexity.

In some environment make sense to tame that complexity, in some other make sense to reduce it!
