I expected the summary to exist somewhere, maybe it doesn't exist.
Never gonna exist, never gonna happen. IMO.
If someone ever did make a singular and definitive "The List" it would be out-dated even before it was published online or in print since each compiler's implementation is always being revised and reworked.
The compiler support list at cppreference is as close to a single sourced list as one can find.
The people doing a compiler's implementation are as loath to do good documentation as the rest of us. Too much to fix/update, too little time.
