Hi @benbchd we needed a similar change and added a filter on the other use of use_filters. I'd like to suggest a change in your filter name for better consistency with the rest of the plugin: duplicate_post_republish_post_taxonomies_use_filters

Either way, let's see what the maintainers have in mind, before committing to a name 😄
