What is the point in logging time hand-flown with sole reference to instruments? It is not particularly difficult, nor does it serve any purpose in its own right. You might just as well log time flying, say, while eating a sandwich.
You log time flown under Instrument Flight Rules because it is just that - a whole different set of rules and procedures from Visual Flight Rules. Public transport operates almost exclusively under IFR, that is why a pilot must demonstrate experience operating under IFR to move up the ladder of qualifications and experience, and so that is why you log IFR as all time, blocks off to blocks on, with an IFR flight plan.
If you look up the JAR FCL 1.080 requirements you will see it spelt out for you.
