Description

https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#nl27-use-a-cpp-suffix-for-code-files-and-h-for-interface-files already exists for old-style code using cpp/h files. However, there is no rule for file extensions related to modules. This is primarily important when having a codebase that mixes both behaviors.

It seems we already are introducing several extensions depending on the compiler. (Ref: https://stackoverflow.com/a/76422027/2466431)

Research direction

Read rule NL27 in the C++ Core Guidelines and review the linked Stack Overflow discussion about compiler-dependent module extensions. Done would require an agreed guideline for module-related file extensions that addresses codebases mixing modules with traditional .cpp and .h files.
