I do not think it is reasonable to drop Python 2 support in the short
term. We have a ton of people still recompiling and installing on older
OSs that do not have Python 3, and I am not talking only about
RHEL/CentOS 6 or older Ubuntu LTS but also other Unix flavors.

Forcing people to recompile Python 3 on those systems just to get Samba
to run on them seem a little bit excessive. (And please do not propose
to embed a version of python3 in our sources or my head will explode! :)

I think the only reasonable way to go to have a smooth transition for
our downstreams is to support both Python2 and Python3 in our code for
at least a coupe of years.

Simo.
