I'd be +1 keeping `iterated_power` since this what we have in RandomizedPCA. But I'll let the reviewers decide ;-) Do we have `svd_n_iter` by the way?

```
$ git grep "svd_n_iter=" | wc -l
        0
```
I'm -1 inventing a new parameter name. Our future selves will then be debating even more options when it comes to adding parameters ;-)
