While working on a [tool to better understand diagnostic flags](https://stlab.github.io/compiler-hardening-tests/), I uncovered several inconsistencies. This may be an issue of ambiguous documentation, but if so, there are many diagnostic messages that cannot be controlled.
For [dynamic-exception-spec][(https://stlab.github.io/compiler-hardening-tests/#-Wdynamic-exception-spec](https://clang.llvm.org/docs/DiagnosticsReference.html#wdynamic-exception-spec)), I see "Some diagnostics enabled by default", but when I click on the one sub-flag it has ([deprecated-dynamic-exception-spec](https://clang.llvm.org/docs/DiagnosticsReference.html#wdeprecated-dynamic-exception-spec)) I expected to see "Enabled by default", but do not.
It could be that "some diagnostics" does not imply "some sub-flags" but that would mean there is no granular control over some default diagnostics.
The complete report of inconsistencies is here:
