I think this would be fine, the question is: will we remember to bump the magic number? You'd have to do it each time you changed the AST, tables, or other (auto- or otherwise) serialized data structures.
Even if we forget, it's better than nothing. If we notice breakage due to forgetting to modify the number, we can check in a quick change to bump it. The worst-case scenario is exactly what we have today.
