Potential feature: Is it useful to make index dl classes configurable?

Is it useful to make these classes col-md-3 and col-md-9 configurable?

https://github.com/projectblacklight/blacklight/blob/master/app/views/catalog/_index.html.erb#L6-L7

Perhaps as a helper method similar to https://github.com/projectblacklight/blacklight/blob/master/app/helpers/blacklight/layout_helper_behavior.rb ?

@mejackreed how about making our own classes and having them extend the styles

.index_metadata_key {
  @extend .col-md-3;
}

.index_metadata_value {
  @extend .col-md-9;
}
