ELI5: why is a pancreas transplant not used to cure diabetes?

I am referring to type 1 diabetes in which the person develops the condition because their pancreas does not produce enough (if any) insulin. Couldn't a transplanted pancreas fix this?

Organ transplants are expensive, risky & have a high chance of failure or rejection.  Patients need to spend the rest of their life on anti-rejection medicine.

If the patient is going to have to take drugs every day, it's easier to just give them insulin which is cheap, safe & effective.
