For server CPUs, sure. AWS, Azure, GCP aren't going to buy Threadripper, nor does AMD's marketing aim it at them.
They talk about "creative professionals" (sound familiar?), and yes, those will have burst tasks that scale to many cores. But they'll also be idling a ton. Most of your time in a work day isn't actually spent rendering something. It's spent interacting with the UI, looking for the right file, or even more mundanely reading/answering e-mail or participating in some WebEx conference. Not to mention all kinds of background stuff. Single-core and heterogenous cores will help you more in those moments (which will likely make up the majority of your workday) than a high core count.
(You can mitigate this somewhat by getting a Threadripper shared by multiple members of the team, but now you're introducing complexity — much higher latency due to networking, most notably. The team won't love that approach.)
