Right, it's definitely a cost/benefit question, I just wanted to take the temperature of the community to see if this is something that others would find useful.
I think your interpretation of those bullets is correct, though it's not clear whether any of that has changed in the past ~year. This specific plugin may not end up being the proper tool for the job, but maybe there's something else out there that could serve the same purpose (perhaps integrating with the DeepL translator pointed out by @IOOI).
I really appreciate your input on this issue, @SDGGiesbrecht! I've admired the effort you put into pre-translating your non-English posts and making this forum accessible and welcoming to non-English speakers.
