Adding "fix" to libunwind is not going to address any real issue with EH while adding an inifinite amount of pain to support new platforms (like wasm for example).

This topic is unrelated to the patch at hand and should rather be brought up with the C++ committee or with other contributors interested in working on alternative models, like herbceptions, instead of trying to dissuade others like the Author here from improving the status quo. 
libunwind in particular is also not technically specific to C++, even if the various implementations of the C++ ABI Support libraries are large users of it and would benefit a lot from it.
