Proton hack won't be acceptable upstream
I learned that Wine and wine-staging doesn't like app-specific code. However, Proton has [a lot of app-specific workarounds](https://github.com/ValveSoftware/Proton/blob/1a73b04e6cdf29297c6a79a4098ba17...). Since Microsoft [famously](https://arstechnica.com/gadgets/2022/10/windows-95-went-the-extra-mile-to-en...) has app-specific workarounds (which Wine needs to emulate for full conformance), our own workaround for Microsoft Office wouldn't be much different on the technical side. On the social side, Wine wouldn't accept stuff like that, but Proton has a history of this.

In simpler words: It might take a long time before I finally get back to looking into this. This is because I don't need to use Microsoft Office right now. I need to dig up the folder I put all the files related to this work. I also need to call someone to make sure I'm still allowed to use the Microsoft Office license from my university. If the better solution from someone else becomes ready before I can look into this, then awesome! Otherwise, other people can pick up my work, build off of it, and send it somewhere where it would be accepted.
