I would like to see something like the GLib GSettings API[0], which is
mature, ergonomic, and works quite well. Notably, programs that use
GSettings can receive signals (roughly GLib's equivalent of ROS's
messages) when a setting has changed.

If nothing else, it might be worthwhile to evaluate and compare existing
configuration APIs like ros::param, GSettings and QT's QSettings to
compare approaches and to see what would work best for ROS. After all -
the important question is what will the API look like, not how it is
