They do not have far-future headers by default, so to get the benefit of fingerprinting you'll have to update your server configuration to add those headers.For Apache: # The Expires* directives get redirected here From my experience, while Sass and Coffeescript provide a lot of syntactic sugar (pretty code features), the fact that exceptions are thrown for invalid code in the preprocessing stage is enough Our application.css.erb however has not changed, so it will not be compiled again.
