1000 /64 links for every /65-126 link may well be the case. However,
plenty of non /64 links exist, and I see no sign of them going

doesn't reflect operational reality no matter how hard you try to
make that claim.
I'm not saying that all IIDs are 64 bits. I'm saying that as a percentage of the Internet, more code is deployed that expects/requires 64 bit IIDs than links than non-/64 links. So if we want to make the standard reflect reality, then we should keep it as is.
