With the recent announcement of the retexturing of iron blocks, obsidian, birch wood and bricks, it feels that 1.13 will also be a texture redesign oriented update alongside the internal technical reform.

Two blocks, acacia leaves and dark oak leaves, have been neglected for quite a while, having to rob their texture from regular oak leaves. Which kind of sucks. They each need a unique texture.

Here are two proposals from a while ago that I feel fit pretty well:

Acacia

Dark Oak

Granted I could just use a texture pack to replace the respective textures by myself, which I've actually already done by the way, but by that logic Mojang should just not bother retexturing stuff in 1.13 and instead release the texture files themselves and give us the option of injecting them into the game manually.

Anyways, that's about it. Let's hope this gets considered.
