--- Comment #8 from Jörg Richter <joerg.rich...@pdv-fs.de> --- To be honest, I can't tell from the description that this option unlocks a libstdc++ that makes no allowance for ABI incompatibilities. If you had a libstdc++ that didn't care about the ABI, similar to boost, this would hopefully attract more contributors and you would have something ready to go if an ABI break does happen. If you advertise such a mode in the release notes, it will surely be used by more than a handful of users.
