Nice question John. LOL Let me pull out my crystal ball...
Sure its on my mind, but I cant say what we will do until I see for myself how things truely end up. Sure if its worst case scenerio and v6 isnt pulling the weight needed and my routers wont fall over from a significant quantity of more specific subnets and all the other aspects line up as needed...yeah possibly we would do it. I think in the moment a decision can be made fairly easily. You can or cant or will or wont do it. However, I have no plans on really having to face that scenerio and I hope vendors and other network providers have the same goal.
I know this is a very simplified answer, but to me its a crystal ball question at this point in time.

Taking the long view: once ISP's are unable to obtain any additional
allocations from the RIRs (due to free pool depletion), there will be a significant focus on recovery of space from less than efficient internal (and possibly client) assignments. I'd expect such space to be reassigned to new clients very small assignments (e.g. /30), with nominal effect on the routing table since the covering routes are already present.
The real question is what happens at that point when a new customer shows up and says that his friend's letting him to use a piece (e.g. /30) of the friend's 'class C' network... i.e. if new native IPv4 service requires a BYOA (Bring Your Own Address) approach due to lack of available addresses, will ISP's turn down new business that doesn't come with own IPv4 block of least /24 in size?
