The free Etnaviv driver only supports OpenGL ES 1.1, 2.0 and 2.1)
OpenGL ES 1.1, 2.0 and OpenGL 2.1 - those are different APIs 
Regarding MobilityArena link, some of these things don’t really make sense since they’re software defined. A2DP is also one of those things - it’s a matter of software stack.
In fact RS9116 is said to support Bluetooth 5.0, but I don’t think anyone actually verified that with any Bluetooth 5.0 peripheral so far. Same with WiFi hotspot - although currently you need to switch the kernel module into a different mode to make use of it, which is kinda PITA; hopefully the driver can be improved in the future to do that automatically via regular interfaces.
