I am, but AFAIU this is not an issue whether dimensionless and
unitless are the same (they are not). The issue is how this
makes a difference in relevant use cases with Calc.
So I suggest that you show several examples where the new behavior is
not what the user will want, and propose a better behavior in those
cases. Up until now, the discussion here didn't show enough clear
examples for me to make up my mind on this issue; perhaps Jay is
unconvinced for the same reason.
