You created a feature request for what, exactly? Upon reading the original post, I don't see a request for features. I see a question that could either be valid in Support or Dev.
If you'd like to make a feature request, please be clear about what the feature should do. Remove limits to the Custom CSS box? Allow importing of CSS/LESS files? What?
Also know that people are likely to suggest alternative solutions, it's happened in other feature request discussions, and sometimes provides viable workarounds that don't require the feature to be implemented. That's just part of having multiple opinions here. As far as I can see, nothing has strayed off topic.
