Better LibreOffice/Word compatibility
Not on the MS side for sure, they've always made sure they don't follow their own spec so they can more easily vendor-lock. Typical EEE from the company that coined it.

.Net cross platform (in VSCode or Jetbrains Rider)
Until they change something. EEE, remember?
