One implication not considered with eSIM is that not the SIM is indeed virtual. if something happens to the device... you need to do much more to get yourself up and running.
An example, my wife dropped her phone and her screen is now completely broken. phone unusable. When the phone has a physical SIM, I can simply take out the SIM and put it in a backup/older phone.
With eSIM only, I need to:
contact the carrier or have an additional phone with additional "backup" sim.
