Just my two cents: we did incompatible changes before such as removing pcre_info, or disallowing 0xD800-0xDFFF range in UTF character sets. After these changes people needed to fix their software (Apache or PHP), and they did it and moved on. We never actually removed a feature, just reworked it.
The original behavior was always odd to me, because it depends on the current subject. I feel that is not exactly consistent. After this change the matching code will be less complex (a little faster and more maintainable), and I think the use cases will not even change because ovector[0]-max_lookbehind character must be kept even now.
