I can’t talk in @phire’s name, so I can’t guarantee that. The next Common Voice release happens on June 30th, so it would need to be merged by then. What I can say however is the earlier the PR is submitted the bigger the chances are that there is enough time for it to be merged before that deadline.
Happy to see that extract-file from the Sentence Extractor is useful! This might also be interesting for others, do you want to create a new topic here on Discourse to post this?
