> Some questions: won't this have an impact on downloading time, once we do not longer compress the payload? What is the advantage of this approach over the one with block_size: 0?

Surely, but this prevents random access which is needed at multiple places in the code (eg to check the compression type).
Github isn't a good place for big files anyway so we should be fine
