I believe it always have been the message that:
* Fortran, Pascal, Cobol, Basic and C will get all the DCL command
   qualifiers, VMS specific language extensions and VMS specific CRTL
   functions needed to compile old existing code
* C++ would be clang ported to VMS close to "as is"

When such a high level idea meet reality, then things can change
a little.

But it makes sense. There are probably not that many old
VMS specific C++ applications out there. For the simple
reason that when C++ for VMS showed up and became
reasonable stable, then VMS was no longer a common
platform choice for new applications.

But there are a lot of stuff developed on *nix and Windows
that need a C++ compiler with support for newer C++ standards
to be able to build on VMS. Including latest versions of
MySQL/MariaDB and OpenJDK.
