Calling Cortex-A35 "full-desktop-capable" is quite a stretch.
Even if it supports the 64-bit ARM ISA, it is a very small and slow core, much slower than even the little Cortex-A53 and Cortex-A55 cores, which were used in the early Raspberry Pi versions.
As mentioned in TFA, at the same clock frequency Cortex-A35 is much slower than the fastest microcontroller cores, i.e. Cortex-M85 and Cortex-M7.
The only advantage of Cortex-A35 is that it has a deeper pipeline, which increases the latency of many things, like interrupt handling, but it allows a higher clock frequency, thus a greater throughput.
Having a MMU, it is suitable for Linux, but using it for a desktop would be ridiculous, as even the slowest Atom CPU from 17 years ago was much faster.
Seems to be the specs are aiming to be a minimum required for Android.
