why did MSDN remove _In_ & co from the WinAPI documentation?

here is the old MSDN SetWindowPos documentation

BOOL WINAPI SetWindowPos(
  _In_      HWND hWnd,
  _In_opt_  HWND hWndInsertAfter,
  _In_      int X,
  _In_      int Y,
  _In_      int cx,
  _In_      int cy,
  _In_      UINT uFlags
);

and here is the new SetWindowPos documentation:

BOOL SetWindowPos(
  HWND hWnd,
  HWND hWndInsertAfter,
  int  X,
  int  Y,
  int  cx,
  int  cy,
  UINT uFlags
);

why is _In_ / _In_opt_ / _Out_ / _Out_opt_ / _Inout_ / _Inout_opt_ removed from the MSDN documentation?

(imo they were useful, giving a quick overview of which arguments were optional, which were modified, which were only read, and which were both read and modified~)
