I think this is useful to have until we completely switch to GlobalISel. I agree with any new effort being low !/$ but since you have made it, I'd vote to get this in.

BTW, I think we can have lit tests to verify this. Dump DAG before and after isel and check with file-check. I am not sure if just dumping with existing dump() routine would dump all the required information but its worthwhile to have a test, IMHO.
