Old player movement in grass and water

I think it would be cool if Mojang added a bit of classic to the (almost) 10-year old Minecraft. Add back the old walking animation when traveling through 1 block deep water, 1 block high grass or 2 blocks high grass (maybe flowers aswell). I think it is a fun little addition to Minecraft and I hope that Mojang likes it too.

You get what i mean, i hope... just the arms swinging horizontally instead of forward.
