I think the main change (accurate handling of strings potentially encoded with multiple bytes) hit a lot of languages from that time in bad ways. I think it's something that more or less had to be done since the alternatives are worse, but we haven't seen a similar issue pop up in a long time. I don't think the lesson applies in many other places. Certainly open to my mind being changed, though!
