I also use it every day, but for apps. Many of the apps I have on my home screen, have "shortcuts", not in the new siri way, but in the "do something/go somewhere quickly in the app" way. I used it to call a person, I use it to open a new tab on Firefox, I use it to add a new todo item, I use it to go to a specific tab on an app.
I would be very sad if it goes away at some point..
Samsung manages to include the "shortcut" functionality you mention AND the ability to reorganize apps through a simple long press. Like a commenter above already mentioned, 3D touch was most likely a solution looking for a problem.
