I have spoken too soon. Khronos lists the VideoCore VI as Vulkan compatible - latest Vulkan 1.1 compatible even [1]. Apparently compute shader support is being worked on for the VideoCore driver [2], which explains why it's missing from current reviews. Functionality to support compute shaders is not even present in current Mesa's git HEAD, let alone on Debian Buster's older Mesa version.
So it not having a modern featureset is a result of more driver issues. It's clear that this hardware has been a surprise release. Oh well, even then using an Nvidia Jetson gives you way better software support for graphics / compute tasks in the forseeable future.
