One passed to U-Boot for fixups and further passed to the OS. This

I assume systemd-boot is implementing the same logic that extlinux.conf
has used for forever, yes?
It is loading the file and then calls U-Boot's implementation of the EFI
Device Tree Fixup Protocol for fixups before passing the device-tree to
the OS.
This devicetree will not contain any U-Boot specific information.
To repeat, it must only have official bindings, yes, regardless of what
project they come from.
Don't expect prior firmware stages to provide any U-Boot specific stuff
whatever official or non-official U-Boot specific bindings exist.
