Why does Samsung disable such a useful feature?

I learned today from my brother that his Pixal 5 has a very useful feature that allows his son to use his phone without actually using it. Essentially he set up an entirely separate user profile for his boy to use as his own. This profile has its own separate Home interface with only apps his son downloaded. I tried to set this useful feature up on my Samsung S10e for my own kid when his own Razor phone got ran over by the neighbor but apparently Samsung disabled multiple user profiles on their phones. Why is such a useful tool disabled on Samsung? Sure there's Samsung Kids but this app is for 5 year olds. My kid is already 16 and has his own job.
