There's no legal or practical reason why someone who has last flown 360 days ago is a better or safer pilot than someone who has last flown 370 days ago. And I seriously doubt that a break of two or three years will make you totally unemployable, at least not with a great number of airlines and especially under the circumstances. In the current situation, there are already quite a lot of pilots who haven't flown for a year or so. Think those who lost their jobs last autumn and haven't found new ones yet (Thomas Cook?). Think those who work for companies that fly only or mostly in the summer and didn't manage to get airborne this summer. Think those who were in the middle of the really lengthy, up to one year long process of application for a job in China before COVID-19 hit. Most of those people are high-quality candidates which any airline would be happy to have - and the circumstances which resulted in them having a long break from flying were far beyond their remit. Who in their right mind would suggest to replace them with someone who might be far less knowledgeable and experienced, not having the right attitude, but having a flight within the last 12 months in their logbook? That would be downright nonsensical.
