I do not know if this helps with your concerns or not, but in the current proposal, _GLIBCXX_USE_CXX11_ABI is only set to 0 for
macOS prior to Mavericks, where libstdc++ is the default.
So _GLIBCXX_USE_CXX11_ABI is being used as it was intended, as a mechanism to facilitate transition.

If you set the ABI back to 0 then yes, you can then mix different std libs. But you are not strictly c++11 compliant. For that reason i do not think its a path we should be looking at as a general 'fix' for the stdlib issue.
