I mostly agree with your analysis, but just to drive home a point here - I don't think that algorithms to beat Chess were ever seriously considered as something that would be relevant outside of the context of Chess itself. And obviously, within the world of Chess, they are major breakthroughs.
In this case there is more reason to think these things are relevant outside of the direct context - these tests were specifically designed to see if AI can do general-thinking tasks. The benchmarks might be bad, but that's at least their purpose (unlike in Chess).
