I am very happy that we are able to add new type of contents (especially maps) to Wikipedia articles. I would like to see more content of the map layer(s) itself and more options and features of these tools.
I would suggest to release the new features only as (opt in) beta feature (for registered users) for a longer time, until most of the bugs are discovered, and then I would roll out as a stable feature for everybody. Maybe this is a slower way, but safer and cause less dissatisfaction in the community and about Wikipedia.
