That's partly what they did. From the article: "One thing we can confirm in advance – the Sunny Cove does not appear to be AVX-512 enabled."
Maybe they also fused off AVX & AVX2 support in the Sunny Cove core as well, we'll see.
And disabling AVX in cores that otherwise support it is already a common thing - see the Pentium & Celeron lineups that Intel currently sells. They don't have AVX/AVX2, even though the cores inside them definitely could offer it.
