Oops, I failed to submit my previous comment ... I too believe that we should be reverting this. I do think that this is invasive enough and something user visible. While I can appreciate that not having to annotate everything with `_LIBCPP_HIDE_FROM_ABI`, it is better to leave the library in a correct state while we figure out how to make the appropriate changes. Reported cases are valuable, but do not necessarily speak to the issue, it is similar to survivorship bias.
