ABIs are important even in the absence of proprietary binary blobs.

They allow different compiler chains to interoperate, they're the basis of FFIs, there are so many situations where I have the source to both sides of some pipe-fitting operation and having a common ABI is what makes my job possible.

ABIs are important within an architecture. But there is no good reason to stretch an ABI over too many variants of the same architecture, except to preserve compatibility with a single binary.
