I wonder if it would make sense to also make a “best before 2018” compilation (excluding the Sequences). The number of articles per year was much smaller, but maybe all of them taken together would be enough.
(Alternatively, maybe include the old articles in the next round, i.e. make it “2021, plus a few ancient articles”. That seems a bit weird, but probably requires much less extra work.)
