This has not changed and will probably never change:
For size and performance reasons, MFC objects are not thread-safe at the object level, only at the class level.

For GUI objects, MFC is mainly a wrapper for the Windows API calls. When modifying GUI elements the corresponding API messages are sent and processed by the control's message loop. So there is no difference between MFC and API applications when changing a GUI element from within a worker thread: Both have to send messages. However, to send a message from another thread, PostMessage should be used instead of SendMessage to inject the message into the queue and process it later by the thread owning the control.

From my point of view using messages to update GUI controls is even simpler than using synchronisation and locking classes for shared objects.
