The reason I think something like this would be necessary is because there are so many pretty looking grasses, it's a shame it's near impossible to use them when building a village or plot. The natural spread is impossibly slow and incredibly limited by itself. This is especially prevalent when you're doing large scale terraforming and paving for the foundations of a city. The default grass from farming seeds is alright, but there are just so many other options out there that look way better.
Another option could be to allow the 'plant grass' function to instead replicate the nearest grass tile instead of simply creating the generic grass it does at the moment.
In short: let me spread/grow my heath biome!
I'm just waiting for it to slowly crawl across my cleared land... And by the time it actually finishes we'll probably be in W11.
And who cares about combat... when you could just be planting grass?
