Makerdiary OpenSK project status

Hi all,
According to the github statistics the makerdiary OpenSK fork is 282 commit behind the google OpenSK project. Is there any plan to sync the makerdiary branch to the latest google branch?

I have a nRF52840 MDK USB Dongle but I did not know which firmware is best suitable for it? As I know the latest google OpenSK branch erase the UF2 boot loader and the makerdiary branch is a 282 commit behind.
