It's a pretty similar shape of problem to NUMA, which servers have managed for quite some time. (Perhaps more similar to big.LITTLE which is not so common in servers but Linux should have decent support for from ARM SoCs) Its a bit of an unnecessary hassle and annoyance, though. I'm pretty sure all the V-Cache EPYCs will have cache on all their dies so there won't be this issue.
