This is impossible and, in the end, not a good idea.
We can not be compatible forever, was this would mean
that we can not improve anything.
e.g. imagine someone would fix the VM to be better.
(e.g. a modern object format).
Do you really request to then *not* do this change because
this VM could not run old images? (and new images would
not run on old VMs?).
Do you want to have a Future or be compatible to the Past?
