No, we're not supposed to set the *system* *default* to python3 yet.
Still, if you have multiple 3.x versions installed you would want to
set the python3 setting to the python version you want to default to
should some program absolutely require python3, so we've got 3 real
settings:

System default - still python-2.x
Python2 - same python-2.x version as the system default
Python3 - what ever version you want for programs requiring Python3

HTH,
