No, not support. Animations still bug out, and you get spammed with errors and stuff. It's more of a crash fix for not being able to load any .png's bigger than 512x512. However, at higher resolutions, like the 4096x4096 required for 256x256 blocks, it causes issues like the one shown in my picture. Texture packs in general seem to mess up on spiders, as well, even a regular 16x16 block one.
Some little back notes on this bug, no, 1.8 will not support high resolution texture packs, it's more of a fix to prevent Minecraft from constantly crashing if you load one. This information is already public (if hard to find, as it was on IRC, and thus is sitting in about 100 personal logs of the channel), as it was requested in the #risucraft IRC channel, and jeb replied saying he added it.
Any way you could try running MCPatcher on it? I'm the author, btw. I don't expect it to work, but it would be helpful to know how badly it breaks so I have an idea how much work I have ahead of me when 1.8 is released.
I see. I'm happy to wait for 1.8 to release as soon as they fix these issues. When we aren't told what's going on, all we can do is make guesses. And yeah, I assumed there was a good reason for the first while. But it starts to seem ridiculous when it goes on longer and longer. But it's clearly still broken, so we'll have to wait. Literally. The alternative appears to be an incredible hamper to our play experience.
In the future, in these situations, more stuff like this would help a lot. Y'know, a little transparency. Some insight into what the delay is. That helps people simmer immensely.
