These instances were detected by searching for files that include Kernel/Debug.h, but don't match the regex: \\bdbgln_if\(|_DEBUG\\b This regex is pessimistic, so there might be more files that don't check for any real *_DEBUG macro. There seem to be no corner cases anyway. In theory, one might use LibCPP to detect things like this automatically, but let's do this one step after another.
