In GraphicsMagick I used the versioning information also passed to libtool. This is useful information since it indicates the available API/API properties of the library. The available values are CURRENT, REVISION, and AGE in order of decreasing significance. For example, CURRENT might be 4. The approach you describe still only works if the major release update always offers additional features over the previous major release.
