The proposal is that it should be documented as being part of the language spec starting in 3.4 (or whatever). So applications that support Python 2.7 can't rely on it, sure. But if I have an application that requires, say, 3.5+ but I don't want to depend on CPython-only implementation details, then I'm still allowed to use it. AFAIK basically the only project that would be affected by this is PyPy, and I when I asked on #pypy they said: <cfbolz> njs`: I think we either plan to or already support this so I'm not sure why this is controversial. -n -- Nathaniel J.
