Why does the earthengine-api package on conda-forge limit the google-api-python-client package version?

On conda-forge, the latest version of the earthengine-api package (and, I believe, many versions before the latest) requires google-api-python-client >=1.12.1,<2. However, the setup.py file for earthengine-api only requires google-api-python-client >=1.12.1. Does anyone know why this might be the case, and if it could be changed to make the conda-forge package not require google-api-python-client <2?

I would ask this via GitHub, but that directs people to use the Google Issue Tracker, and when I tried that, I couldn’t find any issues related to the Earth Engine, which didn’t seem right.
