Hosting companies don't end with enterprise cloud stuff. The availability of consumer grade hardware chips has always been much better than server ones for anybody, but tier 1 vendors.
Just before there was little incentive to chase that market for anything as even the best consumer grade CPUs still were not contenders on core count, ECC, IPMI support, and cache size to compete with Xeons.
But now, even very cheap 3rd gen Ryzens can easily beat mid-tier Xeons: more cores, more cache, ECC support, support for Aspeed remote management. And they are way more power efficient, so making a twin or even a quad system in U1 is possible.
That's already overkill. It's nice having the spare capacity, but it would be absolutely foolish to lease a full-blown EPYC trio.
I can’t see enterprise vendors selling them and I doubt the support is great.
