I probably got lost in the threading, but could you point to where the idea of using an ifn was rejected? I know there was pushback against hard-coding a specific constant, but that doesn't prevent the use of ifns in itself. (E.g. the gather/scatter IFNs have constant arguments that are checked against what the target allows.)
