An now we are full circle.
I remember the first cellphones had no SIM.
You had to give the serial to the telephone company and they will activate your line in that cellphone.
SIMs where supposed to be freedom to move your line whenever you wanted.
Now we are back at the cellphone is the SIM card.

No, because the eSIM provisioning process, as well as eSIM profiles themselves, are standardized, down to how the activation code is represented in a QR code. SIM-less CDMA phone provisioning was never that flexible, as far as I know. Of course, providers can make this as easy or hard as they want to (e.g. by not allowing the reuse of activation codes, tying activation codes to an IMEI, having an allowlist of supported phone models despite eSIM being a standard etc.), but they can already do much of that for physical SIMs as well.
