To me this is a very strange move given the qualification period is calendar year with Aeroflot Bonus. Veery few people were actually affected by Covid-19 before 31 December 2019. The marketing value of this gesture is also doubtful while the cost may actually be existent (if people who would otherwise try to fly more by the end of 2020 do not need to fly more now since they got their status anyways).
Additionally SU refused to extend upgrade vouchers - and this is something that would be much more useful to me in the current situation.
