I'm not interested in encouraging people to use it, that just makes my job
harder. But if you want to use it, it exists.

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 boos

It already has such a mode, and has done for many many years.
