CVEs have been filed for e.g. memory corruption issues with no known exploit or even plausible path to exploit since time immemorial, or at least since time-since-CVE-was-invented. The idea that there is a burden of proof or certainty required to number something with a CVE is a commercial vendor invention.
It's easy to see why people want CVE to work that way! It implies that people numbering potential security issues are doing a fuckload of work for you. But that work isn't free, and CVE has other purposes in the research community. So, no, I don't think anybody is going to talk the kernel people down from this. They're right.
If you want a feed of "CVEs" that clear a plausibility bar, put that together yourself. A lot of people would love to consume it and sell it to their customers; you'll get a lot of uptake.
