It may not be clear from the diff, but in that same file we have code that looks like under "def remove"  we have
```ruby
      options = params.slice(:system_content_view_id,
                             :system_environment_id,
                             :key_content_view_id,
                             :key_environment_id
                            ).reject { |k, v| v.nil? }
```
I am ok with your suggestion, but I was just following what is already a precedent in that very same file.
