No, but when you are going for a high fantasy realism and a lot of your flora looks like paper origami.. it might be good to make another model. (WoW does it too - and I get why of course, more players that can play).
For pieces of content that you cant really scale (because its 2d) then at some later make another one. Skyrim's grass isnt just in Skyrim there many games that have that kind of grass - its not some technical rare piece of model work.
Even Dark Souls that ran on the ps3 has a similar type of grass (though their tree leaves are super 2d lol).
Anyway like I said previously when they get time they should consider it.
