In my particular case, my motherboard is EFI but can boot legacy or MBR. I built it in 2013. Its an Asus Z77 and at this time has 7 SSD's for testing different OS's. It has a bug whereby if one uses GPT EFI boot and I move the cables to another drive for testing the EFI drive will no longer boot. There are no more EFI firmware updates. There is no issue for legacy boot. So all drives are partitioned MBR except Ubuntu 20.10. I didn't even know about the bios-boot partition and GPT until installing 20.10 and I saw the three partitions. That's when I manually tried to partition it MBR which 9 out of 10 times comes up with a warning about not booting and the drive is partitioned GPT. Once in a while there will be a warning but it will remain MBR but after completion it will boot but not complete loading the OS. I suspect most people don't even know about the bug and have not reported it because they just let Ubuntu format the drive automatically. If they're using legacy boot and don't examine the partitions they have no idea how it was partitioned.
