I don't disagree. However, you can see the knee jerk reaction by others here to make it look like Softimage immediately and continue on like its the same. It's not and you will have to adapt.
It's public knowledge that Maya can be run without its interface while having another interface riding on top. I'm pretty sure Pixar's Presto software is doing just that. It's entirely possible to customize it to your liking but how much maintenance will that take? A custom UI that mimics Softimage by someone in the community isn't going to do anything to make anyone at AD redesign Maya. Instead keep being vocal and explaining on the list and forums about why work flows are better in Softimage.
