AMD does sell Threadripper with the same enterprisey guarantees as they do for Epyc, at least in regards to ECC.

>Quad-Channel DDR4 ECC Memory Support >With the most memory channels you can get on desktop6, the Ryzen™ Threadripper™ processor can support Workstation Standard DDR4 ECC (Error Checking & Correction Mode) Memory to keep you tight, tuned and perfectly in sync.

ECC is also supported in the desktop class CPUs and chipsets.

ECC isn't the only feature, please don't focus on that at the expense of missing the point. They do some market segmentation between TR and Epyc and it is material.
