Comment (by iamdmitrymayorov):

 Agree with spacedmonkey. No doubt that it is possible to style the button
 using the id. But if you are using bootstrap and less and do something
 like this:
 {{{
 #submit {
  .btn;
  .btn-primary;
 }
 }}}
 After compiling, your css file becomes 2Kb heavier because  all the
 bootstrap button styles are now applied one more time to our tiny button.
 If there was a possibility to add class this could be avoidable. I agree
 it's not 100% semantically correct but good in terms of saving bandwidth.
