Feature: option to remove fill from sprites.svg

[growdigital]

One of the advantages of using inline SVG (by Ajaxing in the sprites.svg file) is that the elements are styleable using pseudo class selectors eg ::hover and ::active. See here for examples:

It may be good to have an option to remove fills and strokes from all elements (although that does make generating PNG fallbacks a bit more problematic…), possibly by adapting SVGO plugin along these lines:
