This is kind of a loaded question.

"Google" doesn't understand anything, as it isn't one being. Google has also as many average employees as any other company, and they will also come up with bad, corporate, ideas.

Honestly the worst part about the LLM age is that everyone is suddenly an "expert", and that is why we get shitty things like A2A or MCP or whatever the next "shiny" overengineered thing is.

Just like with any new technology, people will crawl out the woodwork to establish "standards" just so they can claim fame, money and attention that comes with it.
