Some blocks do not use multipart, and use up more file capacity than it should

Cauldrons, Flower Pots, Hoppers, Redstone Comparators, Redstone Repeaters, Tripwire, Vines do not use the multipart, and it uses up more file capacity than it should. I have a solution resource pack, which decreases about 70kb.

I know this is kind of a suggestion, so I don't mind being this bug to be invalid, or WAI, but I will be very happy if this pack was used. It took me a few hours to make this pack.
