There are many questions are that more or less self-explanatory and can add points to your main one:

• Does the root user actually need a home in /root as in separate from other users, probably for safety reasons
  
• What's the harm in running things as root, you can nuke your system easily
  
• If the root user has a home does it mean you should use it like any other home and store files and software in it, maybe only administrative
  
• Should the root user shell profile be customized like any other users, and does this pose any risks
  
• Should the root user have a command history, or should it be erased everytime to start from a new clean environment
