replaceAllUsesWith + eraseOp is indeed not supported at the moment. That's because both function update the conversion mapping and the second one would overwrite the first one. I have a PR in preparation that will allow it, but it will still take a while.

The only API that is fully supported today is replaceOp. You can write replaceOp(op, {val, Value()}) to replace only the first op result and drop the second one.
