This could make the transition way simpler than having to flash a USB drive and boot from it — something that the average person wouldn't bother doing.
So I figured that if a person is tech savvy enough to figure out how to boot into the BIOS and disable Secure Boot, they would be tech savvy enough be able to just create a bootable USB instead - and I reckon that's a far more easier-to-explain and achievable goal, especially since most major distros these days can be installed with Secure Boot enabled, so you can skip the BIOS instructions for the most part.
Hence why I canned my idea, and why I don't think Operese has any value either (sorry - but happy to be proved wrong).
