small feedback / suggestion

Hello people, I want to make a small suggestion about environment tweaking.

I imagine Most people make rather large grass block areas, and remove most of their short / tall grass from those areas. What if you made a small percentile chance that the grass would grow in, like weed growth. 

Imagine copying the growth rate for amethyst buds, making it a little smaller chance, and changing the source block from amethyst blocks to grassblock, and the output from amethyest cluster to grass and or flowers. 

You'd have a RNG chance that if you had a 3x3 area of pure grassblock, every few ticks would possibly create a new grass clump on a random grassblock in that same area. Potentially a flower or weed included.

It would create more work but feel a little more like " my backyard is growing grass and i must interact to maintain ( cut the growing grass ) .
