I am about to write up a more elaborate technical rationale describing the problems with multiboot on ARM:

Doesn't seem to exist? A search for "mulitboot" doesn't seem to throw up the one you meant either.

Try again now. As mentioned "I am about to write ..." ;-)

Thanks, Andre.

So, is having a more generic solution really needed?

Not necessarily needed, but useful, I think. As described above I don't see any technical obstacles of doing it in a more generic way, so we could as well go ahead with this. On x86 from time to time the need for additional binaries pops up (early microcode loading, for instance), so why not be be prepared.

I agree. There have also been occasions where people doing disaggregation have wanted to start multiple initial domains, requiring additional modules at load time. I don't think being generic and extensible is costing too much here.
