Overhauled Diamond Generation

When I start a new Minecraft world, I usually spend longer than I would like in the caves trying to find a reasonable amount of diamonds. Even when searching through huge caves, it feels like every vein of diamonds I do manage to eventually find only has 1 or 2 ore blocks within it. This might just be because the cave generation splits the ore, but it is still quite disheartening when you spend so long looking for such a well-known ore just to only receive a few, especially when searching through caves is obviously the intended way of mining for them.

I suggest that the generation of diamonds should change to something similar to before the caves and cliffs update, where diamonds were much rarer but you would often find them in much larger veins. Whilst you may spend just as much time mining after this change, nothing would compare to the satisfaction of finding a huge ore vein of an actually usable amount of diamonds, rather than finding a lot of veins with few ores within them. It would also mean that nearly every time that you spot a diamond ore, whether that be next to you on the ground or on the ceiling of a huge cave, it's more likely than not going to be worth your time to collect.
