Is this statement an obvious fact?

In nature, there are many examples where little to no change occurred in hundreds of millions of years: Sharks, horse-shoe crabs, cockroaches, etc. They reached "evolution perfection" or to put in a less flattering perspective: They have reached genetic Ossification. That is, they found a place where change is simply not required because it just works. I recognize that these species named have an inherent selection bias because they are the ones that survived. Countless other creatures that could not adapt perished.

I know the idea of ossification in software development is considered a dead end. And for apps, this is largely true. However, when we talk of Internet protocols that are crucial for its survival: DNS, SMTP, BGP and others, serious care should be considered before any change is implemented.

Few people are saying, "let's tinker with DNS to improve it", and there are fewer cases where such changes get implemented. But they do happen after very careful and considered review. And they happen very quickly when survival is at stake (major security breaches e.g.). DNS works so well that we seldom think about it. Bitcoin is not an app. We should study and follow the trajectory of change management that other crucial Internet protocols have undergone. If a change were made to DNS with unforeseen catastrophic consequences, the Internet could shut down. If a change were made to Bitcoin with unforeseen catastrophic consequences, the Internet of Money™ would shut down. Perhaps that is the very reason why we don't "tinker and make changes" to crucial Internet protocols.
