I know this is a late response, but I think that this is a good idea and it could attract more developers from different backgrounds to build creative apps for the UNA ecosystem. I would like to see more UNA integrations with Wordpress for hybrid sites. For example, maybe a developer who creates sitebuilders will make an app so our members can build their own websites within our UNA sites. Especially with so many Wordpress developers who are trying to get their plugins out there, this will give them an outlet.
