Just throw some tokens at the problem. I’ve vibed up a Rust Crux hybrid app that runs well on macOS, iPad and wasm and does some pretty complex xml manipulation and other document work. Absolutely smokes electron and you get native UI.
one does not just "throw tokens" at a problem, Ai is not that capable, and we are talking about MS Office file format, likely a NP hard problem
On top of everyone else’s great points, if you make your own “fork” of something, then you have to consistently maintain it. Which can be done with tokens, but an extra cost with something that’s not as user tested.
