OK, so UnicodeError_xxx is important for codecs, but surely this sort of 
argument could be made for lots of things.
Don't forget that for each function added to the API,
all other implementations have to support it forever.

Unfortunately, UnicodeError_xxx are not the only new functions.

Various others have been added:

int Py_EnterRecursiveCall(char *where)
void Py_LeaveRecursiveCall()
int Py_ReprEnter(PyObject *object)
void Py_ReprLeave(PyObject *object)

HotPyModule_GetFilenameObject
HotPy_CompileStringExFlags

and a few others.

Individual functions are not the problem,
I'm sure all of these can be justified,
its lack of process and review that bothers me.
