That's not my experience. It doesn't say a whole lot, it just says a person is bored a bit and is confident in his ability to learn new things, you can filter for learning abilities by looking at what the person achieved; doing new stacks is just one metric. Also it's sometimes the type of people who care more about learning/trying new tech on the job than actually helping the business (for exmaple by introducing GraphQL because they read about it in a blog and it looks cool, not because they really think the business needs it).
