If you tell me that every enterprise on the planet can easily get a /48 routed at no cost, then indeed that's probably the right way to go.  I will defer to others with more experience in these matters to tell me whether or not that is so; my understanding hitherto has been that it is not.

I think it was Brian who did some analysis a few years ago on just how many “large sites” are out there.  It’s not *that* scary a number.  Though nor is it small.  Obviously if you include homenets the meltdown is massive, but no one in the homenet wg is proposing PI for homenets.
