Errors when calling ambiguous methods are unlikely to be a big hazard – at least we haven't found them to be. Most ambiguous calls are very unlikely to actually occur, which is why that change makes a lot of sense. The big breaking change is the array indexing one – that will very much require adjusting multidimensional array code.
