I read your recent article on ossification. Thanks for that insight, very educating. 

I had a question, and hear this from a perspective of me simply just trying to understand. Is there a definitive process to “declaring” ossification? Or is it something that just gradually happens over time? It would seem (based on my understand, or lack thereof) that the protocol will ossify naturally when it is ready to. Am I understand that correctly? 

 I assume that definitive ossification of any FOSS software is impossible.  But would also like to hear from devs. 

 Ossification of software is impossible.

Ossification of network protocols is inevitable.

 Right, it's unprecedented for a protocol to be DECLARED ossified. No one can authoritatively state that development is done until we're far enough in the future that we have hindsight.

Ossification is an inevitable result of a protocol becoming so widely adopted that it becomes impossible to coordinate updates.
