I think you're missing that person's point though. This evolution implied in the thread was:

1. Write "logging" data (observability, whatever) 2. Someone else starts using that to drive behavior 3. Change your logging, because it's just logging right? And stuff breaks.

To state it another way, anything you're emitting, _even internal logging_, is part of your API/contract, and therefore can't be changed carelessly. That problem is the same no matter what technology you use.
