Yeah, pretty much so.

Yes. And there are many dimensions to "what is best".

IMHO, your turning things upside down here. ELF is _known_ to work

Yes, I know this. But good to see it stated explicitly.

No. Let's keep this technical, please; and good engineering
demands looking at the problem from all relevant angles, and
then we reach consensus. If a deadlock happens, Ron gets to
decide, that's his job as the daddy of this project :-)
Voting is for people who like arguing better than they like
having an actual solution for their problems. I hope we're
above that <g>.

Right. So my base is *not* "ELF is best", but it is "ELF is just fine
for this, so why would we need another format, with all infrastructure
overhead that requires?". So please start by explaining what is bad,
or even just sub-optimal, in using ELF here.
