Indeed, because I don't know what a good solution could be.

Closer to MOP already existed before asdf imposed anything on version numbers, so asdf has to provide a way to define exceptions for such cases. The versioning scheme of Closer to MOP was ad hoc, because nothing existed that could have been adhered to. It must be possible for libraries to move from non-adhering to adhering in a smooth way. Frankly, I don't care how that's achieved. If I can solve this by adding something to the system definition, that's fine with me...
