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.

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.
