Are there plans to add raspberrypizero2w_64_defconfig config?

Raspberry Pi zero 2w is completely capable of running 64-bit OS, since it contains a quad-core 64-bit ARM Cortex-A53. My application needs 64-bit (aarch64). Are there any plans to create 64-bit configuration/definition for Raspberry Pi zero 2w?

I'm happy to do it myself, but some pointers on how to do this correctly would be highly appreciated.
