It seems that the apps whose save dialogs show a combobox in place of a filter list are creating a `QDialog` and setting the Mime types list with `QDialog::setMimeTypeFilter()`.

Yes, and I did more investigation myself, and all the glue is in plasma-integration. Some changes might be needed there too (or maybe //all// the changes will be needed there, we'll see!)
