New way of importing XMP presets to Lightroom mobile via "Import presets"?

Hi! In a YouTube tutorial I discovered a new method of directly importing XMP presets to Lightroom Mobile on Android devices, but I haven't found any official news by Adobe to confirm this. Who can share more information of this will also be available on iOS or if this is already a feature that is being rolled out? Currently, this method using DNG files seems to be the only official one for both iOS and Android.
