I'd guess the best would be to have a special VMSTATE that means

No, the best would be to have a serious migration format, based for
example on ASN.1 which Michael Tsirkin was playing with. We cannot keep
bolting more and more stuff on top of the current protocol, especially
since adding a new protocol is not that hard (old machine types can keep
the old protocol).
And even more so with the old format being ambiguous. We haven't decided
yet what to do with subsections of structs, have we?
I hope to test this week the prototype I sent.
