Ever since homeassistant has moved away from adding integrations in yaml to the UI, it is cumbersome to be not able to install home-assistant in a repeatable manner since it involves lot of clickOps to get the integration configs setup. I get that this is done to reduce the barrier to entry for non-tech savvy folks but is a pain to setup and maintain for developers who would like to manage their automations and configs through git. It would be great if we would have it work both using yaml and also through the UI so that people who still use yaml can set things up as config and not have to manage everything through the UI.
Sorry that ship has sailed. And YAML will always be available for specific uses. See: The future of YAML - Home Assistant
