I’d love this feature too. Why not add it as an optional thing to enable and let users decide? Maybe just put a big warning in the docs and make it opt-in?
I really hate adding knobs - it increases the amount of work I need to do to maintain and support the project.
Long term, I'd like to port the ansible modules over to being maintained internally by the dokku/omakase project, and then maybe that could be a plugin that folks could run from within their deploy.
