Just my 0.02$ as a user: I was also a confused/put-off by `alpha` and `l1_ratio` when I first explored SGDClassifier, I found those names to be pretty inconsistent --- plus I tend to call my regularization parameters `lambda` and use `alpha` for learning rates. I'm sure other people associate yet other meanings with alpha/use other names for the regularization parameter. `l1_reg`/`l2_reg` would be much better/conciser names, it would be nice if those could be used all throughout sklearn.
