      8 General guidelines on imports:
      9 
     10 - 'stats' depends on 'tags', but 'tags' shouldn't depend on 'stats' or 'trace'.
     11   'stats'/'tags' and 'trace' should remain independent, where possible.
     12 
     13 - Packages should not be split between artifacts.
     14 
     15 - 'internal' packages should only be imported by packages within the same
     16   artifact.
     17 
     18 - Since we are trying to remove dependencies on Guava (issue #1113), we should
     19   avoid adding any new Guava imports here, especially in the API.
