Is there a reason for making all columns relative?

Typically I wrap my rows and cols inside 'sections' which have their own padding top and bottom. I sometimes choose to make elements inside those columns stick absolutely to the edges of the section. With cols as relative now, it's less trivial to do so.

Applying an override of..

[class*='col'] {
    position: static;
}

does the trick, and I can't seem to find any drawbacks. Although I'm wondering if there's a good reason for relative in the first place? Please correct me if I'm wrong or missing something.

Cheers!
