Yes, but you didn’t mention anything that would suggest a need to ‘maintain’.

It doesn’t change.

Many people keep swapping gear in so they can learn BGP on Cisco edge gear or run clusters on salvaged IB.

OP is not that person.

I gotta agree. I setup a homelab originally to start learning more about virtualization, Kubernetes, etc. It was painful, required time to fix my mistakes, and I hit my head on the ugly realities of distributed hardware. But it was also experience I could (and did) apply to my job.
