Hi Inada-san, as you may remember, I wasn't happy with the deprecations of the APIs in PEP 393, since there are no C API alternatives for the encoding APIs deprecated in the PEP, which allow direct encoding provided by these important codecs.
AFAIK, the situation hasn't changed since then. We can't just remove access to one half of a codec (the decoding part) without at least providing an alternative for C extensions to use. Py_UNICODE can be removed from the API, but only if there are alternative APIs which C extensions can use to the same effect. Given PEP 393, this would be APIs which use wchar_t instead of Py_UNICODE.
