More reason to run your infrastructure using open source software in your own datacenter. OpenStack has been around for closing in on two decades, running clouds and being mostly governance-drama-free.
It's not surprising that a proprietary ecosystem built on open source software locked up behind a gate doesn't make a worthwhile ecosystem for building open source tooling against.
OpenStack is one of the most complicated platforms in existence and finding suitably talented admins is very hard.

Until they stop being open source. Like, you know, LocalStack.
Running OpenStack for this is a massive project cost compared to spinning up a few local services, and the operational mess is on a different planet from "I need to fake a handful of API calls on my laptop". Self-hosting still means updates, drivers, and k8s/OpenStack glue code. Nobody sane are doing that for local dev, use Minikube or Podman if you want DIY and still like weekends.
