empty __init__.py files or not?

[Morganizer]

changes.rst says
"The init.py file import statements should now contain the following:
from ZenPacks.zenoss.ZenPackLib import zenpacklib
CFG = zenpacklib.load_yaml()
schema = CFG.zenpack_module.schema"
Which is in contrast to what I have been going by on the wiki, for example https://zenpack-sdk.zenoss.com/en/latest/tutorial-http-api/modeler-plugin.html Which is right? What would the symptoms be if the empty files were impactful?
