Since I'm planning to support various dependency injections, view events and/or various hooks, converting from a PHP template will allow for cleaner implementation and will expose dashboard to existing twig resources.
I plan to use this as an example case for injecting one or two canned plugins until a plugin registration process can be implemented.
Will develop the initial controller, services and location tree as initial backbone to build out.

I think it would be prudent to have a simpler plugin option for items where a full module is overkill.
