@import only substitutes with the file contents if loading in a .less file (needs .css files too)

Using @import will only substitute with the file contents if it is referencing a .less file. This needs to support .css files too.

It's intentional, it gives you the ability to import css without compiling it.

And that by-design prevents us from being able to combine multiple CSS files into one - which is our requirement.

Why not have it so if you don't want to combine do something like this @import 'other.css?nocombine'

It allows us to achieve both our desired functionalities. I tried bypassing the check via monkey patching, but failed getting it to work.
