This won't suffice: that means that code /in archives today/ that has
truncated id's won't be able to be checked out by 1.3.0. The use of a
panic vs warning today won't change this in any meaningful way. That
said, I still think that a panic rather than a warning is more useful:
it demands correction, rather than allowing it.
