Why does PX4 standard firmware not support Frsky telemetry?

Hi all,
Any news about the FrSky telemetry on px4?
After reading the documentation at the PX4 User Guide - FrSky Telemetry I found as explained here pixhawk-fmuv5-stm32f7-and-later that for a Pixhawk 5X no special cable is required, just connecting the smart port to any enabled serial port (Telem2 in my case).

I checked that FrSky telemetry works:

But, when I select “Discover new sensors” from the telemetry tab of my Taranis Q X7, the RC finds lots of meaningless sensors (like F501, F701, etc.). Moreover, I do not see one of the most important for me, the battery voltage (VFAS).

Having no experience with Lua scripts, I thought the values of these sensors would be mapped into something readable by the Lua script. At this point, neither the LuaPilot scrip nor the lua yaapu script worked.

I saw the post here Pixhawk 5x - FrSky Telemetry ID Reference List?, and it seems that the best solution is to give up to FrSky telemetry.

Do you know if there is a way to get correct data from the FrSky telemetry, considering my setup made by a Pixhawk 5X, a Taranis Q X7 RC and an X8R receiver?
