Why are there undocumented exports in user32.dll ?
Are they items that M.S. did not get around to developing ?

Probably undocumented for internal usage.
Many are left-overs from Windows 3.
They're still there for backwards compatibility, but are deprecated because they shouldn't be used in new code.
Many others are documented, but not with the exact name given, e.g. CharNextExA and variants fall under CharNext (http://msdn.microsoft.com/en-us/library/windows/desktop/ms647469%28v=vs.85%29.aspx).
And some actually are documented, so I'm not sure how you got this list.
Here is an interesting link :

Thanks.
Someone probed user32.dll to get that list.
