No two environments are the same. Instead of looking for a like for like total replacement (even though you actually don't use all VMware features or use some only because they were the only way possible in VMware's ecosystem and not because they're actually any good (vRA, Log Insight)), evaluate your actual needs and what do you need to run under what conditions. You'll probably end up discovering that any of Proxmox, OpenStack Nutanux, oVirt, Ganetti, Kubernetes (with or without KubeVirt), Nomad (with or without VMs) will cover most if not all that you need.

You will also probably end up discovering your costs drastically inflate. There is a reason why companies stick with bundled products. Find a way to bundle that mismash of software you mentioned into a single pane of glass with a 4 year support guarantee and you will be rich.

You will quickly find out why it hasn’t been done and why Redhat and Microsoft look so promising after all

Ha, nonsense. VMware products are notoriously super expensive. From discussions with people at organisation switching to alternatives, their cost are going down 30-50%, with all the added benefits of a proper modern orchestrator instead of an obsolete hardware simulator. (Stuff like having a way of securely introducing secrets or security authenticating workloads, or integrated deployments, healthchecks, etc.)

Also, "bundled" stuff constraints you. You're forced into using VMware's crap orchestrator or log management tool because it's the one that works best with the mess that is other VMware products.
