Yup, I can't help but think Intel is paying for this to be a thing, and the AMD drop of 1x series is simply to avoid legal implications should they get called out on it.
But I will hold final judgement to their blog, they need to explain this DAMN well before I decide I need to save and drop several hundred quid on a new mobo/cpu/ram for my gf's perfectly good Skylake system post 2025!.
