I have always thought that farmland as an English word means land used
for production by growing things - cabbages, cows etc. Hierarchy then
led to arable, pasture, horticulture. But what do you do with managed
woodland eg coppiced or pollarded or left to semi-wild animal
populations eg deer, swine?
Fields also have a habit of having several uses determined by a farmer
- pasture/grass for silage, arable/grazing stubble. These also change
over time.
Climate has a highly important role in determining what farming is
carried out - west side of England is predominantly pasture, east side
of England predominantly arable. Wales and Scotland also have altitude
to modify farming practice
Can we agree a hierarchy and notation method to this deceptively simple
question and then update the wiki.

I would say yes, as I believe both arable & livestock is farmland.
I concur with your frustration about 'huge multi polygons', especially when joined
to other features such as roads & rivers. I believe a few mappers were keen to
fill in the gaps rather than map accurately. Personally I think there should be one
polygon per field, but I admit that makes for a lot more work.
I see no benefit to mapping individual fields as separate polygons
tagged as farmland if adjacent fields are also farmland. Could you
explain why you think this is best?

Large polygons make future editing very difficult.
It is very beneficial to differentiate between arable, pasture and hopefully we
can get real meadow back from the misuse it has received.
Farming use changes, mapping individual fields allows farmland types or other
changes to be maintained far easier than if it is part of a huge polygon.
All in all it goes to make for a better more usable map.
