As local variation in the UK has been steadily decreasing West for a few hundred years, and continues to do so, and it is now passing through zero degrees variation to become Easterly variation, the runways' magnetic alignment will continue to decrease, and at some point it will make sense to rename them 26R and 26L. Variation certainly ain't going more Westerly, at least not in the UK for now.
