I also questioned[1] if such backward compatibility was needed, and had concerns[2] about a version file being heavyweight and over-engineered. This is a lot of new code (possibly harboring its own bugs) for a situation unlikely to arise, and which becomes ever more unlikely as time passes. Also, unlike long-lived (years or decades) resources, such as a repository or pack file, for instance, for which a version number makes sense, this file is very short-lived, which makes it even more difficult to justify adding this much machinery for something so unlikely to arise in practice. The overall aim of this series to fix these bugs is laudable, but I would be happy to see this one reduced to just a "bug fix" patch without all the backward-compatibility machinery (and wouldn't mind seeing patch 1/2 simplified[3], as well). Thanks.
