Perhaps, but that's not really up to users. Linux distributions, for example, control this pretty directly. You can alias it, but why bother? If you know that Ubuntu links python3, every Ubuntu installation that gets python from apt is going to do this.
Yes, but on all reasonably recent distros (including all current "LTS" releases) just `python` will also get you python 3.x. If there is still a python 2.x on your system you'll have to type `python2` to get it. So it is up to the user... to upgrade their system. You really don't want to work on a system that's so outdated that `python` is still python 2.x.
