Maybe we can limit the SCSS dependency by checking in the rendered CSS, so only people working on the style would need a sass compiler.
I was thinking of that too, but I used this approach on one of previous projects (both, SCSS and generated CSS files were under git) and it just gave me headache as the coworker was changing CSS and committing those changes which leaved SCSS and CSS files out of sync.
Obviously not the way to do it.
But we could easily just agree not to do it, and state that we don't accept pull requests that have direct changes in CSS.
I think this will work out nice, css doesn't change very often.
