Mine definitely seems bigger than when I first started attending, although that was almost 20 years ago and the growth has been gradual. We've always been kind of a big parish anyway. But we took the chairs out last year after reopening once the lockdown was slowly rescinded so everyone could have space, and even without all the regular parishioners having returned yet, and opening up the hall as overflow, we're quickly approaching standing room only.
My parish is one that is very Orthodox in practice, and we are definitely booming compared to what I've heard from some Byzantine parishes. It would not surprise me if that is because we are adhering to authentic Byzantine traditions in the same way TLM-only parishes are adhering to authentic Latin ones.
