I have no idea what would be acceptable. Amazon seems to still support
2007-era APIs... I guess we could use a deprecation mechanism to get rid
of very old API versions (discourage their use before getting rid of them)

I understand why it's easier to support only one... I just want to make
sure that's what we wanted to do, since I thought otherwise. Hopefully
someone with a longer history in the project than me will chime in :)
