Whilst I appreciate that development is based on LE10 going forward, I believe there is a case for a complete update of the Raspberry Pi 9.2.x family to not only use Kernel 5.10.x but also in regards the 4B update Firmware to support version 1.4 as well as the 400.
It would be great to close of 9.2 development with one final big bang, especially for users of BCM2835 RPis.
There is a 4B discussion on the RPi Forum here:
