We tried this. I was tasked with automating popular software installs into fresh VMs. I think some of my scripts for doing so are on my github - wordpress and some dashboard software, at least.

offerings were published on the main page and afaik no takers. We migrated off whatever hypervisor we were using onto wok/kimchi and finally to proxmox, so my scripts still work, but proxmox has turnkey linux "quickstart" servers now as well as lxd, so there's less reason to use my scripts.
