Yes, very likely carriers (and phone manufacturers) are in the process of making the transfer easier, but it remains more complex than a physical SIM.

I wonder how the "same QR code" might work, I mean, let's say you have your e-sim on your phone, and someone steals the original QR code, if all is needed is to scan it, then the thief could "install" your e-sim to another phone, there must be something else in the procedure to guarantee the de-activation on your phone and allow the transfer, the point is if it is doable with the old phone not functioning.
