If you look at the statistics section on the JLPT site you can see that overall there’s a big range in motivations for taking the test - from academic reasons like getting into university, through to professional reasons, and then there’s just people who want to measure their own proficiency.
I agree that this isn’t really news yet, it’s speculation. However the articles seem to focus on the problem of assessing people better for professional situations. If the new test is better suited for this then I imagine for people who had that as their motivation it’ll make both test takers and businesses happy!
That said, I highly doubt that a test which is exclusively business-focused will end up being the sole test, purely because the JLPT folks will be mindful of people whose focus isn’t business - some of them won’t care about how to schedule meetings for instance!
