It's about time that ICAO switched to using TRUE worldwide for all bearings. Apart from convenience (for 99.9999% of aviators), the cost savings would be significant - no more repainting of runways numbers, re-calibration of VORs etc.

Admittedly a tiny number of GA pilots who are still flying around using their compasses would have to learn the magnetic variation in their local flying area and add or subtract it from their wobbly compass bearings. But if they are capable of correcting for their compass deviation then it is hardly a big calculation to also correct for variation.
