True. It does document a flag in the ELM327 configuration registers
though, and it was originally meant for adding 7/8 bitrates (e.g. 87500
as a companion to 100000). I never got around to implementing those
bitrates, though.

I find opportunistic documentation helpful for future reference and
to give casual readers hints - can I leave it in there anyway, or is it
deemed an eyesore?
