Description: Python 3.12 compatibility: adjust submodule imports
 importlib imports behave differently in py 3.11 and py 3.12: py 3.12
 requires explicit imports of the submodules.
 .
 While fixing this, reduce the imports to the used submodules. Currently,
 the base is still imported automatically.
