 **Requirement**: C++ preprocessing must produce identical output regardless of compiler flags.
 
 Therefore, feature test macros such as `__cpp_explicit_this_parameter` should
-not be used directly. Instead use the following approach for feature-dependent
+not be used directly. 
+
+**Recommendation**: Feature-dependent code should create `#define`s in generated headers based on CMake options, with a fallback for users who just vendor the include/ directory.
+
+Instead use the following approach for feature-dependent
 code generation:
 
-1. Check for availability at CMake time using, for example,
-   `check_cxx_source_compiles`.
-2. Create a CMake `option` (e.g. `BEMAN_<short_name>_USE_DEDUCING_THIS`)
-   with a default value based on detected support.
-3. Generate a `config.hpp` with a `#define` macro set to the selected option.
-4. Use this macro in place of the feature test macro.
+1. Create a CMake `option` (e.g. `BEMAN_EXEMPLAR_USE_FEATURE_QUUX`).
+2. Depending on the option, you may want to implement a check for its availability at
+   CMake time, using, for example, `check_cxx_source_compiles`, and set the option's
+   default value based on the result.
+3. Generate a `config_generated.hpp` with a `#define` macro set to the selected option.
+4. Create a `config.hpp` file that wraps `config_generated.hpp` with the following logic,
+   providing fallback defaults for users who vendor the include/ directory:
+
+```cpp
+#if !defined(__has_include) ||                                                 \
+    __has_include(<beman/exemplar/config_generated.hpp>)
+#include <beman/exemplar/config_generated.hpp>
+#else
+#define BEMAN_EXEMPLAR_USE_FEATURE_QUUX() 1
+#endif
+```
+
+5. Include `config.hpp` in your headers, and use the resulting macro instead of the
+   feature test macro.
