I think it depends greatly on experience levels both in total and on type. When someone is still relatively new to aviation then, at least in my experience, it tends to take a little bit longer before performance is back to pre-break levels. The same is true when someone has recently converted to a new type. With a few thousand hours total time and say at lest a thousand or so on type I find that the return after a break is typically not problematic. I hope airlines and/or regulators will take this into account when flying picks up again. I suppose a combination of a relatively inexperienced captain and a relatively inexperienced F/O, yet neither of them necessarily low time on type as per the regs, could be the most problematic.
