Good. The more software vendors require UEFI, the more arm board manufacturers will have to support it.

As an embedded developer I don't hate device-tree-only devices per se, and I have the skills to make any distro (that supports ARM) work on any board, but I absolutely do not have the patience to do it.

FWIW there exist UEFI implementations for Raspberry Pi 4 and 5, they can be used to boot Windows 11 aarch64 images as well as 'generic' Linux distro images, so I suppose they will support this one as well.

I was curious about this, so I looked it up just now. It looks like the project providing UEFI for the Raspberry Pi 5 is abandoned, and compatibility with newer board revisions is reported to be broken (if I correctly understand their "end of support" message on the repo).
