Probably way too harsh - BP gives the minimum that you can try and plug your own code into.

html5bones is clearly taking a different route, by making everything and every tag as clear as possible. Everything is commented to give someone starting out a good explanation of why all this stuff is there.

eg. in HTML5 BP:

  <script>window.jQuery || document.write('<script src="js/vendor/jquery-1.8.3.min.js"><\/script>')</script>

Newbies are now completely lost. What's going on here?

html5bones:

  <!-- An <aside> is used to enclose content that is additional to the 
  main content but not essential. If it were removed, the meaning of 
  the main content should not be lost, but the content of the <aside> 
  also retains its meaning. -->
  <!-- ARIA: the landmark role "complementary" is added here as it 
  contains supprting information for the main content that remains 
  meaningful even when separated from it -->
  <aside role="complementary">

I heavily applaud this idea - too much of HTML best practices is completely arcane to most of the people using it. The more people understanding what this stuff actually does the better for everyone.
