I wonder about the location of this file. Since we call them Guarantees I feel this is aimed at our users and our developers.  Reading the document gives me the same vibes; aiming at users and developers. So I would like to have this information to be at the user documentation.

Maybe adding it to https://libcxx.llvm.org/DesignDocs/ABIVersioning.html would be better.
