Totally agree.

It appears Anthropic developed this "standard" in a vacuum with no scrutiny or review and it turns out it's riddled with horrific security issues, ignored by those hyping up the "standard" for more VC money.

Reminds me of the micro-services hype, which that helps the big cloud providers more than it helps startups with less money even with some over-doing it and being left with enormous amount of technical debt and complex diagrams costing them millions to run.
