[Idea / Meta EIP] Protocol Maturity and Ossification Framework

A post on the Ethereum Magicians forum proposes a Meta EIP establishing a protocol maturity and ossification framework, with stages running from Active to Stabilizing, Ossification Candidate, and Ossified. The author argues Ethereum has 'document finality' through EIP Final status but lacks 'protocol-property finality,' and proposes classifying individual protocol properties rather than EIP documents, maintaining a registry of properties and their maturity, and requiring future Core EIPs to include an Ossification Impact section. The proposal explicitly does not aim to ossify Ethereum today and lists open questions about what process and level of social consensus should be required to mark a property as permanently unchangeable.
