Servo (robot) life state/ occult in Sims 4

I hope that robots/Servos are a playable life state like in Sims 2 and Sims 3. Their plumbob has a gear around it. Instead of trait chips, this time their creator Sim could use the "Upgrade" interaction already in the game and directly upgrade the robot:

Upgrade...

• Ability to feel emotions (Servos are usually always "Fine")
  
• Cleaning robot (Autonoumsly clean house & fast cleaning)
  
• Nanny robot (Takes care of children)
  
• Garden robot (Tends to the garden and has Lvl 10 Gardening skill)
  
• Waterproof (Doesn't gets shut down if swimming in pool, washing hands or in rain)
  
• Better battery (Battery need drains slower)
  
• Feel love (Ability to have romantic interactions)
  

Besides that Servos are different from regular Sims in these areas...

• Energy need replaced by Battery need. Servos charge in a charging station.
  
• build relationships with electronic appliances like microwaves, fridges or washing machines (like SimBots did in Sims 3!)
