I suspect you find the RA mechanism which assigns prefixes to a link simpler to use because that configuration information is tied to the lifetime of that particular link.
That premise does not hold when you are delegating address space to a network behind that link.

If you were taking that approach, it would imply ephemeral addressing and flash renumbering.

Simple and cheap on the operator side likely implies complex and costly on the end-user side.
That might not be a good tradeoff. There are many more end-user sites than operators.
