I have written a quite large document using sphinx, and underwent several iterations with external translators. The translation workflow works fine, however I noticed that when I delete phrases/content in the .rst source files, then there still always remains a 'MsgId' recording in the .po files.
I would like to clean these 'ghost' records from the .po files, to avoid running into unneeded translation costs.
Is there a way to solve this? Can sphinx-intl be instructed to remove entries from the .po files for when the msgId is no longer present in the .pot file?
