after py2 EOL, is it safe to repoint python?

[snippsat]

For me python and pip always point to version choose as global(system wide).
Because i always use pyenv Simple Python Version Management.

Why pyenv?

• pyenv will install Python or other Distribution(Anaconda,PyPy,MicroPython...ect),set it as system wide installation(or run it in a shell seesion).
  
• No more using python3 or pip3 or sudo or --user when pip install something.
  
• It's always python and pip to version set as global,and pip install requests to global version.
  
• It's safe and will not mess with your OS,can go back to default pyenv local system or remove all rm -rf $(pyenv root)
