What I'm asking is that
(1) The other values be documented as reserved, rather than as illegal.
How is that different?

In debug mode, or release mode? -1 on release mode.
These two requests seem slight contradictory. Non-official __xxx__ names
are reserved for future use but not illegal now for user-use, and
user-generated examples do not raise an exception. They simply do not
get any special attention unless and until given an official meaning.
Then too bad if that breaks code.
So by analogy, reserved type value would be ignored, neither corrupting
data or raising errors, until put in use. But I don't know how
easy/practical that would be.
Or maybe more to the point, how expensive a check would be. Not checking
names for reservedness is the easiest thing to do.
