I often see discussions like this and I also recall reading some emails 
about alternatives formats already in progress (sorry I can't find now).

(Without really knowing much about this ...) are there proposals already 
written for an alternative to ELF?

Something new but already used elsewhere? Or to be invented/implemented at 
NetBSD first?

Or something else already in use (like Mach-O)?

Any PRs or URLs or email threads about this I can look at?
