Intel's dropping support for the UEFI Compatibility Support Module (also known as 'level 2 compatibility') for their new platforms come 2020. Come then, you'll be unable to natively boot from devices with a MBR partition table, which was the primary method to boot the system from BIOS. Curious (!) to see how this will affect things like older graphics cards and PCI/PCIe NICs that only (AFAIK?) have VGA BIOS support, and hook in to the system boot through interrupt capture.
Personally, I feel this isn't even trying to fix something that ain't broke, but rather, breaking what was already fixed with UEFI for little good reason. However, perhaps I'm underestimating the effort it takes to validate BIOS compatibility and peripheral emulation on new hardware...
