Just as a follow-up, I have looked at upstream activity, and it seems that there is an on-going effort to make rope compatible with Python 3.
I tried to refresh the packaging with 0.10.3 and attempted a build for Python 3. There are still a lot of tests that do not pass on Python 3.5, which is acknowledged in the following bug upstream: https://github.com/python-rope/rope/issues/171 So, I guess we should monitor how this issue goes before going further with rope. I believe spyder still makes it an optional dependency, so it should not be a blocker. Ghis
