We have no plans to add any more changes to 9.2, even more so as the new rev 1.4 RPi4 seems to contain incompatible hardware changes and 9.2 won't boot on it.
If you really feel the need to run 9.2 you can simply change the kernel configs and build LE on your own - see the instructions in our wiki https://wiki.libreelec.tv/development-1/build-basics
so long,
Hias
