The RPM is measured speed via PWM signal capture  which is output 
from fan.
So should we have the fan[1..n]_output_rpm?

No. I hear you clearly that you for some reason dislike fan[1..n]_input.
While ABIs are not always to our liking, that doesn't mean that we get
to change them at our whim. If that is not acceptable for you, I can't
help you. And you can't change inX_input to inX_voltage either, sorry.

My opinion is only to not use "input" as this is not really the input to 
fan.
