I haven’t reviewed the entire series yet, but where did we discuss requiring python 2.7 for everything?
I remember that we required a newer python for the test suite and some of the release scripts, but we explicitly didn’t include other parts then.
I’m pretty sure we break some legacy platforms if we change things for swig, and some of the installed python scripts.

You are right but for now, I'm fine with syntactic
compatibility.
My goal is to simply being able to run our build
and test scripts with Python 3. I don't plan on
switching over or even make it mandatory.
I expect the code to become "cleaner" by e.g.
using centralized functions and symbolic constants
instead of octals.

I went for the stream write because that's what we
already use in various places.
