Or you could just sell a SIM that's programmable as an eSIM if you send it the right codes.
Then people can still pick up SIMs if they so desire, use eSIMs in legacy devices with no special support required (a SIM is really just a smartcard that accepts certain commands), or it can even be a "reprogrammable" physical SIM that you have to stick into an adaptor to load a new eSIM onto it.
When the cheap Chinese stuff to manage these things starts to appear, then you know they have become mainstream.
But a supplier could easily deal exclusively in "eSIMs" and just give their customers a "reprogrammable" physical SIM if they ask for one.
