Ya,but the newest Cortex-M chips (M7, M22, and M33) do not even support bit-banding, so I wouldn't rely on that being around forever.
Not quite sure why ARM removed it. Maybe there were performance costs to all instructions due to the extra hw/decode, while bit-banding only helped a small number of instructions.
If anyone has more info, would love to hear!
