Honestly, I don't like this except for "important" comments.

A "small" comment, e.g. one that doesn't quite fit on a single line, now takes
4 lines instead of 2.  Which is really annoying and IMO tends to break flow.

If you don't like

  /* gnu
     style */


  /* whatever
   * this is */

could you live with

  // c99/c++
  // comments

(I know we currently deny those in checkpatch, but that's easy enough to remove
if we're changing policy.  I have no idea why we don't like them in the first
place.  Or other c99 features like mid-block or control declarations, for that
