+ The 2.x series of Python is due for deprecation and will not be maintained

+ Debian "buster".
+ .
+ If upstream have not moved or have no intention to move to Python 3, please
+ be certain that Debian would benefit from the continued inclusion of this
+ package and, if not, consider removing it.
