In principle, this is very important (maintaining backward compatibility
such that an external plugin will work with a VM that might not be at
the same version level). In practice, it is unlikely that a Squeak user
would mix a newer FilePlugin with and older VM, since most folks obtain
and install both at the same time.

A conservative approach would be to introduce the changes into the VM,
then update the FilePlugin, SocketPlugin, and OSPP about 12 months
later. But really I don't think it's necessary to be so conservative
in this case. It's not as though we're burning the disk packs.
