I dont think any other format has the functionality of sections and
segments with segment and section permissions etc.

Are you planning to mimic 1-1 lld to ld linker script functionality ?

Do you by any chance have a proposal of how the lld linker script would
look if there is a difference b/w ld and lld linker scripts ?

Maybe the first version could be just ELF centric.
