-    if (!SupportedTarget)

Thanks for asking!
I think `isSPIRVLogical()` would be better here, as other SPIR-V flavors are 
not compatible with graphics (including compute shaders).
Ideally you could also add a `TODO: revisit this once we figured out how to 
handle PhysicalStorageBuffer64 memory model`.
