By fat:

by extra i mean what is reflected in this diff. Above all this extra code (https://github.com/twitter/bootstrap/commit/5ad5dde1e24f668cf9b720dd59fc2a7d4808c0b3#L1L216) is generated which is sad as most people aren't customizing there less builds at all, let alone the column size.

Making sure that only the defined number of columns is generated is really import to me :)
