To each their own. I mostly figured out why, and I did not want to create too much tech debt in my homelab with brittle split-DNS and PostUp/PostUp wireguard configurations. I already had ansible and templates setup to move back to the VM and docker-compose. I did learn a fair bit on CoreDNS, so that was a worthwhile experiment.

I didn't mean for you, I meant for me. I have truenas providing storage to my cluster but can easily just run a VM there.

I think you're approach is absolutely valid and didn't mean to seem like I was dismissive. Apologies.
