Isn't part of STIR/SHAKEN to make it easier to determine the ingress provider, or the provider of last blame?

Since some don't, something else needed to be tried. Exactly. And that doesn't require an elaborate PKI. Who is allowed to use what telephone numbers is an administrative issue for the ingress provider to police. It's the equivalent to gmail not allowing me to spoof whatever email address I want. The FCC could have required that ages ago.

I can't simply block traffic from a peer carrier, it's not allowed, so there has to be some mechanism to mark that a prefix should be allowed, which is what Shaken/Stir does.

The problem was that there was zero to negative incentive to do that. You don't need an elaborate PKI to tell the ingress provider which prefixes customers are allow to assert. It's pretty analogous to when submission authentication was pretty nonexistent with email... there was no incentive to not be an open relay sewer. Unlike email spam, SIP signaling is pretty easy to determine whether it's spam. All it needed was somebody to force regulation which unlike email there was always jurisdiction with the FCC.
