Absolutely. I haven't gotten in the weeds of K8 volumes, but certainly have done a lot with Docker volumes including adding some PRs to fix some issues I've ran into. There is a lot under the hood with Docker volumes. With how DBs like to optimize their IO operations, I'm frankly a little amazed how it somehow mostly works between the DB -> orchestrator volumes -> file system.

It works totally fine on k8s with iscsi/fcoe/nvme-backed volumes provided remote targets themselves offer sufficient performance for your db workload

K8s mostly drops docker volumes code (and many other parts of docker, TBH). You can pass a random mount point or even a raw device and it will have only the overhead of kernel IO code for namespaces, overhead you hit anyway.
The only "docker graph" stuff is in OCI container data itself.
