Since this is only adding a new export to libc++, not changing/breaking existing ones, I don't think it should be grouped with the ABI-breaking changes in v2.
The usual promise is that upgrading libc++.so.1 will not break apps compiled against an older set of headers, not that you're able to compile against a new set of headers and then run on an old libc++.so.1.
That is, even if the use of the new export is put under a #ifdef, it seems like it ought to default "on".
