When mappers always use farmland for crops and meadow for cows (or
horses), the data consumer will never find an area cows-or-plants.

Please help me with the cleanup of the area around Reet. I honestly
cannot remap all landuse=farm there based on imagery, although I know
the area more or less. :-)
I doubt that everything that is mapped as farm right now, has to
become meadow/farmland. It's meanly the meadow and other "grass" that
you cannot see from the sky.

That's what some want to do in The Netherlands, a mechanical edit from
farm to farmland.
On the other hand, you will never know for sure whether farmland is
for crops, as the wiki in some languages states that you can use it
for crops and meadows.
This is similar to the problem of wood/forest where no-one knows
whether it is an area used for timber or just a place where you find
some trees.
