A rough criteria for what should be in 'base' is: everything required by
Prelude.  I say only a rough criteria, because there are currently
plenty of libraries in base that aren't required by the Prelude, but are
there because splitting them off into a separate package would be
overkill.  (Also at one stage I was using a different criteria:
everything required to bootstrap GHC).
