Honestly I think there’s a lack of talent for that, not only to develop the protocol, but to support it. How many of us really understand OSI?

OSI is just a model, there’s not all that much to understand there. It’s simply a way to categorize network technologies using a common language.

OSI is an entire networking stack designed by committee that died from disuse [1]. The only thing we now remember of it are the functional layers within the protocol.

For example, people sometimes refer to TCP as a "Layer 4" protocol even though (a) TCP predates the invention of Layer 4 and (b) TCP is a square peg that does not exactly fit into the round hole that is Layer 4.

I wish we could forget the other remnants of OSI like x.509, ASN.1, and LDAP. Those were the things good enough to be used for real systems, and I'd still rather crawl over broken glass than implement any of them.

Imagine how bad the rest of it was.
