Comment (by pmav99):

 According to the docs, {{{lib/python/script/setup.py}}} contains functions
 that
 > can be used in Python scripts to setup a GRASS environment and session
 without using grassXY

 Not having the ability to import the {{{grass}}} library from a normal
 session means that you need to already be in a GRASS session in order to
 use the functions that can create a session (chicken-egg problem).

 After making the grass library importable, the whole problem of
 bootstrapping the GRASS session will finally be much easier to be
 resolved.

 Or course, we will need to review and if necessary improve the
 setup/cleanup functions in {{{lib/python/script/setup.py}}} and, most
 importantly, write tests for them. But after that is done, it will finally
 be possible to refactor/simplify the bootstrapping code in
 {{{lib/python/init/grass.py}}}
