There is no known (real) hardware with V and without the complete B extension. B was indeed required in the RISC-V application profile from 2022, earlier than V. There should not be any relevant hardware in the future either. In practice, different R-V Vector optimisations in FFmpeg already depend on every constituent of the B extension anyhow, so it would not work well.
