Micropython on nRF5340?

I understand that Nordic has completely converted to Zephyr going forward, and will only support that OS for future development, but are there any technical limitations preventing community ports of Micropython for the nRF5340?

The nRF51 and nRF52 series already have ports of Micro/Circuitpython available, but I've found absolutely nothing regarding the nRF53. Obviously the SoC's complexity and full feature set can't be completely supported, but I'm surprised that there's not even a basic single-core build for this powerful platform at all.

Is it possible to reuse the nRF52 port on the nRF53, or are the architectural differences between them too pronounced? I'm not nearly proficient enough yet to attempt implementing a port myself, but I'm curious why seemingly no one else has tried. Is it simply not possible due to reasons beyond my novice comprehension?
