The Guile project has taken this idea pretty far; they’re generating ELF object

and C together into one executable image, letting GDB understand some of your 
data), switching to a machine-specific format would be a pretty drastic change, 
when we can currently share the files across machines.

Although it does indeed sound like a big change, I don't see why it would prevent us from sharing the files across machines. Emacs can use standard ELF and DWARF format on any platform if Emacs is doing the loading. And there should be some software-engineering benefit in using the same format that Guile uses.
