Tachometer speed returned rather than absolute fan speed?

Hi,

In medias res, I find this interface cumbersome:
http://lxr.free-electrons.com/source/Documentation/hwmon/max6650#L31

It returns tachometer speed rather than actual fan speed when you deal
with the fan1_target interface. That would be way more convenient for
end users like me.

Is there any reason for not returning absolute fan speed? I guess,
this would break the behavior now. However, that would be a really
useful convenient feature. Is it possible to add a new interface for
that?

Cheers, L.
