FWIW, the existence of this flag and the TargetCXXABI abstraction (which predates the flag, but might otherwise be more simply factored/implemented with inheritance rather than switch tables) came up in discussion D135326 <https://reviews.llvm.org/D135326> and D119051 <https://reviews.llvm.org/D119051>. (eg: the RecordLayoutBuilders are split by Itanium and Microsoft - but there's loads of triple checks throughout including for C++ layout choices (eg: `getBaseOrPreferredBaseAlignFromUnpacked`, empty base handling, etc) that aren't captured by the TargetCXXABI abstraction) & so the question was where to put this next C++ Itanium ABI fix which is currently applied to Itanium in general, except for PS, Darwin, and Clang ABI <= 15.
