This was deprecated in Android 4, so a long time ago. A few phones still have it because the manufacturer hacked it back in, but they are the exception. You should assume these days that any phone you buy does not have this unless you know otherwise.
I've read that Sony added it back to some mid-range handsets (which have more limited storage) but not the higher-end devices. If you want that to change, better contact Sony rather than tell us!
