Silk touch enchanted items need tweaking

Hi, I think that after the 10 years or so that silk touch has been in the game you should adress a little incosistant thing about it.

Every silk touch item can cause block which needs silk touch to be broken to be dropped. This is a little bit incosistan with the game mechanics: for example the item to optimally break dirt is the shovel, the item for leaves is the the hoe, the item for stone is the pickaxe... so you would epect to be able to silk touch only the blocks meant for that tool however it is not like that, with a silk touch pickaxe you can silk touch every item in the game such as grass. I think that silk touch should work specifically only on the optimal blocks for that tool: you need for example to break grass with a silk touch shovel to get a grass block, not a random tool with silk touch.

I hope this feedback goes under rewiew!
