Dear Common,
Although many major shuls are near or at regular levels, many minyanim that cater to the elderly are still closed. As well as smaller shuls that never had a big crowd. Also, people are more comfortable with minyaim inside and outside the work place. Impromptu and scheduled vacation minyanim are at an all time high.
It is a good question how this plays out for Rosh Hashanah. Some places put a lot of work into squeezing out as many seats as possible. They may feel it is wiser to turn people away. [Or use it as an excuse to work less.] Also, yeshivos do not want to risk being shut down for the beginning of winter zman. Additionally, there will be much less of a pilgrimage to Umann this year. And less people are not heading to Eretz Yisrael until after succos.
