This sounds like something you should take up with the C++ standards committee. They decide how the language works.

I would rather Microsoft go the route of Microsoft extensions to the standard..  And I assume the organization of a C++ project is not something the C++ standards commitee deals with.  I asked about organizing code in a project with sub folders.

You can add filters to C++ project source files and header files. They are kind of like logical folders in that they organize the code for you, but do not actually create a sub folder in the file system.
