In the future, it will be used to support adapters that have multiple
completion event vectors (via MSI-X or similar).

No, completion vectors and completion channels are orthogonal.

You would need to update the kernel midlayer to handle multiple
completion vectors, and then patch a HCA driver to support it too.
