Seems like an effort to stick video en/decoding behind graphics drivers as a vendor neutral approach instead of relying on VDPAU or VA-API. These efforts should equally apply to Windows and Android as well as Linux.
Unless targeting flagship devices, most likely OpenGL ES drivers are more stable than Vulkan.
Hence why OpenGL ES on Vulkan is now a thing since Android 14, that is the only way Google has found out to force OEMs to up their game on Vulkan drivers.
