Honestly, a better solution would be an open-source IODD-type device, because sometimes I still meet old devices which do boot via USB DVD drives, but not flash drives.
But Ventoy is a second solid choice, especially with newer devices, where such limitations are basically non-existent :)
It is still required, as Google had to do the same with Android, offering multiple search engines and presenting them to the user (at least that happened to me with my phone), but after doing it in Windows 8.1, Microsoft probably thought that it was enough compliance to keep "those nagging EU politicians" away.
