Hm. We have a few header files that are similarly macro-generated (and sometimes the macro code is behind ...) but I also thought we had this generalized with variadic arguments.

I have been mulling an idea regarding a top-level header file choice also signaling minimal language standards opening the door a little to C++14, C++17, C++20, ... . I should open an issue ticket one of these days.
