#define RHINO_SDK_MFC in V7

If I create a Rhino V7 C++ plug-in using VS 2019, it compiles just fine except when I #define RHINO_SDK_MFC in the stdafx.h file. I get the following compiler message:

Build started…
1>------ Build started: Project: aPlugIn2019, Configuration: Release x64 ------
1> — rhinoSDK.h — Building Release Rhino V6 plug-in
1> — rhinoSDK.h — Using Visual Studio 2017 compiler tools.
1> — rhinoSDK.h — Using v140 Windows Platform SDK (MFC 14.1, VS 2017).
1> — Rhino C++ component links with libs in “C:/Program Files/Rhino 7 SDK/Lib/Release”

This message is generated beginning at line 192 in the rhinoSdk.h file when _MSC_VER >= 1900. (VS 2019 is 1920 or higher).
Why does defining RHINO_SDK_MFC also generate a message indicating the usage of VS 2017 and Rhino V6?

These are just messages that were never updated from V6 and VS 2017
