As remarked earlier in the thread, why bother having the rule at all.
We all managed just as safely for decades before the rule was introduced by JAR around the year 2000. The CAA's own safety review showed no improvement in safety statistics following introduction of the rule (or for that matter introduction of BFRs, annual MEP tests etc) and if "uncurrent" I would rather take another group member pilot with me who was familiar with the aircraft than take some instructor who may never have even sat in that particular type before.
