In my work I've find three common types of objective:
Static objective with parameters necessary to have to start a proccess, like agreement values (process duration, links, names and etc.),
Dynamic objective with time sensitive data, like cmd_vel or mission waypoints,
Mixed with both types of data.
For static objective it's not handy to store one-shot data in pubsub topics by it's raw API, and worse to get them from topics. There is a need for helper functions to store data in static objective and get them from it by some convenient API like from dictionary, for example.
