I am denying that it is as serious as you say. exFAT has been around for nearly two decades, and nearly everything from the past 15 years supports it. If you choose to format an SD card as FAT32 because your 20 year old device doesn't support exFAT, that is entirely reasonable. Maybe a 20 year old device doesn't have much use for >4GiB files either. On the other hand, if your device does support exFAT, there isn't any reason to avoid it. The lack of file size limit should be a particular advantage (with 1080p and especially 2160p video, >4GiB files are common).
