Interesting, this subject naturally brings me to how bitcoin is being developed. The protocol is definitely ossifying more and more over time.
Bitcoin and Nostr are both protocols serving different needs, one is money, the other is information, or speech.
The real world analogy for Bitcoin would be gold, which is a very physically and chemically stable metal, hence its successful use as money.
What would be the real world analogy for Nostr? Perhaps politics.
Unlike Bitcoin, there is no single direction for Nostr, nor a concept of a hard fork.
NIPs might increasingly resemble a legal framework. But one were you can ignore the part that you disagree with, not change them.
