Actually the basic USB fallbacks and simple charging are all handled through passives (resistors) and 100% of Type C cables will support them. Sadly that's the only thing you can depend on by inspection.

Communication of port capabilities are described in the spec; not sure about cable capabilities though.

You'd think that companies couldn't mess up a simple resistor. https://docs.google.com/spreadsheets/d/1vnpEXfo2HCGADdd9G2x9... proves that wrong.
