You can easily have python3 implemented as shell script setting up
PYTHONPATH to whatever your particular Python installation uses.

Python itself does not install as python3, so this is not a configuration
supported by Python anyway.

Also note that it's easy to write a sitecustomize.py which takes
care of whatever platform specific side-by-side installation
you want to support with an OS or distribution.
