can you explain this point? i think if a new developer starts with
python3 now (and i have plenty of examples at my company) they just
use `python3` on the commandline, shebangs, venv, etc. I dont see the
confusion we would create.

I dont think that's the right decision. PEP 0394
(https://www.python.org/dev/peps/pep-0394/) allows distribution not to
ship `python` at all:

https://www.python.org/dev/peps/pep-0394/#for-python-runtime-distributors

* If the python command is installed, it is expected to invoke either
the same version of Python as the python3 command or as the python2
command.
* Distributors may choose to set the behavior of the python command as follows:
** python2,
** python3,
** not provide python command,
** allow python to be configurable by an end user or a system administrator.

it is my opinion that that's what we should do: not ship `python` at
all and have users/packagers/developers use either python2 or python3
as needed, and not to reintroduce `python` at a later time.
