Switching out bold descriptive value weights with numerical 700 values

Created by: guylepage3

What’s the reasoning for all the use of the bold !default;keyword value throughout _variables.scss/variables.less? $label-font-weight: bold !default;

Shouldn’t this be a numerical weight value for consistency? like weight: 700;?

Maybe i’m nuts, but this would allow for easier overrides of an h1 css selector's weight for example.
