 This change would take place in a major version, so some level of backwards-compatibility breakage would be justified. In cases where it caused problems with existing code, fixing it could be done quite trivially by either switching to single-quoted strings, or escaping the backslash.
-In order to reduce backwards-compatibility issues, particularly with JSON in string literals, ''\u'' which is not followed by an opening ''{'' will pass through verbatim (instead of being interpreted as an escape sequence) and not raise an error. This means that existing code like 'json_decode("\"\u202e\"");'' will continue to work properly. On the other hand, ''"\u{foobar"'' will raise an error.
