Answer 1

a br tag doesn't produce a CSS box and hence little can be done with it.

Only practical case is clear. i believe drupal used it at some time. interestingly CSS 1 spec. refrained from doing anything to br. http://www.w3.org/TR/REC-CSS1/#br-elements. no doubt applying some css on it doesn't invalidate the code but will cause little effect.
