Assuming you could somehow make 16 /8s available, do you really think that anyone would accept the idea of allocating
all of them to a single RIR, let alone the one in North America?

I tend to doubt it.

So ARIN’s burn rate post-runout really isn’t all that relevant.

The wasted effort of people whose time is better spent deploying IPv6.

Which I would rather have those folks focused on something useful than wasting their time on this.

The /10 did not require modifying every system on the internet or even any systems on the internet. It just required 
setting aside a block.

Even then, it was actually more effort than it should have required, but it was pretty minimal. OTOH, it provided an 
actual usable solution to a real world problem.

What you are proposing just wastes a lot of people’s time with nothing to show for it.
