I've been chatting with @Ivangayton / HOT OSM about how to resume some of the past work around improving the geo widgets that @zestyping was such a key part of, and also develop the ideas for the work into a more cohesive vision. There were community discussions around this at the most recent ODK Convening in late 2019, and a variety of forum discussions. We're just wrapping up on an initial document to describe the aspirations and so it has not been discussed with the TSC yet. The hope was to get additional eyes on the ideas and work with the TSC to figure out the technical feasibility and fit with the ODK project. Then if we can agree on a clear scope and plans, move on to identification of resources to make happen.
EDIT: I think there is a lot of overlap between the above and our proposed roadmap ideas.
