Additional explanation of these comparisons is below.
Exhaustive
The 7PK authors acknowledge that the goal was not to be exhaustive, stating that the kingdoms are only focused on the most important implementation-level coding errors that can also be automatically detected by tools. The CWE-1000 and CWE-699 views include weaknesses found in design, implementation, and other SDLC phases. Even if a weakness cannot be detected automatically, it is included in CWE, so the scope is wider than current tool capabilities.
With respect to weaknesses, CWE-699 and CWE-1000 have the same goals for exhaustiveness. However, some weakness pillars in CWE-1000 are too abstract to have a good fit in CWE-699. With CWE-699's use of categories and CWE-1000's explicit intention to avoid them, CWE-699 is generally going to be the most comprehensive graphical view of CWE, although the CWE-2000 view always lists every entry.
