Is the expectation that snapcraft would drive pipfile directly, or would it still expect to use it via pip (or, perhaps, pipenv)?
Good to know! 
I wonder if an interim solution, to enable early adopters to easily use snapcraft, could be to set up snapcraft to handle Pipfiles by running pipenv run pip freeze and then using pip install -r on the resulting output?
(It seems to me that if snapcraft doesn’t support it first-class, then people will have to maintain a requirements file in their repo just for snapcraft, which feels like a barrier to adoption. Am I missing an obvious workaround?)
