If you just want to do relative imports, then that's the purpose of
the explicit relative import syntax ("from . import sibling" etc). You
can also do dynamic relative imports by passing "__package__" as the
second argument to importlib.import_module.

If you're looking to read *data* files relative to the current module,
then the API you're likely after is `pkgutil.get_data`:
https://docs.python.org/3/library/pkgutil.html#pkgutil.get_data

And if you're looking to access files relative to *__main__*, then the
metadata atribute you want is __main__.__file__.

So it's currently still really unclear what you actually mean by
"package root", and what related metadata you see as currently being
missing at runtime.

Cheers,
Nick.
