Now pip 10 is out, of course, I discover that I've lost the implementation of `get_supported` in pip.pep425tags. It's my fault for not remembering I had used it. Is the suggestion to use the `_internal` import, or carry a copy of the pep425tags code myself, that I have to keep up to date with the internal pip copy? That would also involve me copying the `glibc` part of the code. I see that the `wheel` package has an old copy of that code too, which doesn't deal with manylinux wheels. You probably saw that `pip-tools` ended up vendoring the whole of pip9 .
