At the moment, I have a strong guarantee from the python core developers that my code WILL keep working until 2020, and I will NOT have that guarantee if I migrate to python 3. I would laugh at this, if it didn't make me cry first. See my comments at [4].
So, if I am left to my own devices, I will not consider any porting effort until late 2019, to make sure that between here and 2020 I will need to do porting only once from 2 to 3, instead of who knows how many times from 2.x to 3.4, then from 3.x to 3.x+n at every new Debian stable release.
