In your roadmap you listed pdf support, so hopefully your system already has abstractions in place to handle multiple input formats without rewriting everything, no? You'll just have to pull-in an odf crate (or vibe code one).
I understand that it's extra work for you, but if you take a step back and look around you maybe you'd see the greater good.
Yes, we support reading .doc, .pdf and read/write on .docx. Perhaps there is some greater good here, but I can tell you it's a burden for at least one competitor in the ecosystem. We basically cannot market into Germany now until we've baked this in. This certainly doesn't hurt Microsoft.
Then of course maybe that isn't the point which is fine. I'm actually surprised at people reporting on here that ODF is their preferred format. I've worked professionally in documents for two decades and never come across one other than as accidental output from Libreoffice. So perhaps it is my ignorance on display and Germany never was a viable market without this.
