Review comment:
It's required, because
```
def load(path: String): DataFrame = {
// force invocation of `load(...varargs...)`
option("path", path).load(Seq.empty: _*)
}
```
If we remove this method and always call `def load(paths: String*)`, we
should make sure the behavior doesn't change, and we still generate "path"
option if only one path is given.
