   > And if we think there are no concerns for creating one metric group twice
   
   There are concerns; it prints a warning to the user as it is not how the API is supposed to be used. If any components need access to a shared group then this group should be created once and passed around as needed.
   Things were implemented this way on purpose to prevent components from interfering with each other by accident.
