You can set up notifications for when friends and family leave or arrive at a place — making meetups a cinch. And so no one’s privacy is compromised, they’ll be notified when you set one up. You can also use parental controls to set up alerts and notifications, so you know when your child has arrived at a friend’s house or departed from school.

It doesn't bother me because all you have to do is drag the cursor around with your finger - directly on the cursor, and the cursor gets bigger and comes out from underneath your finger to be visible.
The magnifying glass was removed because it's not needed with the way text editing can be done now.
I hated the magnifying glass because it would throw me off, like trying to aim at something underwater. With the way it's done in iOS 13, just touch the cursor and drag it around. Or tap to make it come to your finger, then touch and drag it around.
