End of the article mentions the following:
Android was not mentioned by either Arm or Collobora, so I’d assume Arm will still focus their resources and provide closed-source Mali GPU drivers for Android, while expanding their support for Panfrost on Linux.
android emulators can ship their own userland drivers, this is how a lot of android emulators ship turnip drivers which boast expanded vulkan feature support and sometimes better performance. and considering the open source nature, i can easily see someone porting it for rom usage especially considering how much of a meme mali drivers are on android and emulation community
