The field(s) I'm in use double blind and it's broken for a host of other reasons. It's really hard to build off a string of work for example. Students (eg the ones writing papers) are often bad at the anonymization requirements. On the other side, the reviewers can often form an opinion on likely authors (whether correct or not). And then up one level (at the editorial / program committee level) that anonymization goes away since they need to check for reviewer conflicts, etc.
