It's an exercise opportunity, or a take-a-break opportunity, and to me it looks cool, you can mow your lawn with a European scythe (do a couple of swaths a day) and it's not boring, each cut taking some precise control.
pictorial overkill :
Normally you get rid of the windrow after you've done the day's cutting with a leaf sweeper and a few trips to the back fence to add to the enormous haystack (how big will it get?).
In the spring I have to start over at the front before I get done in the back, but you can't stall a scythe with long grass so it doesn't matter much.
It's not hard work and is a pleasant way to spend an hour.
