Personally, I log IFR when, err, I'm flying IFR in an aircraft legally authorised to do so.
Given the complications of modern licencing, I modified my logbook several years ago to have a separate column for "by sole reference to instruments"; unsurprisingly it's a smaller total.
If I'm not following Instrument Flight Rules, I don't log IFR. If I'm in visibility above VFR minima, I don't log "sole reference to instruments". If I'm IMC, I'm also IFR. If the aircraft is on PtF and thus the paperwork says "IFR proibited" I don't log IFR. When I wasn't qualified to fly IFR, I didn't log IFR.
I do deliberately set up quite a few, but not all, of my longer trips so that I do fly IFR and build up a few IFR hours - but that so far as I can see is perfectly reasonable.
Is it all that difficult?
