I think you are misunderstanding the situation. It wasn't a case of, "It 
works but it's slow." The situation was that in order to take 
performance of the network stack as a whole up to the next level it was 
necessary to remove the Giant lock. Because the original I4B code didn't 
work without the Giant lock, and because no one stepped forward to fix 
that, the code had to be removed.

In this case it was 100% about the latter. In addition to the fact that 
without volunteers there is no project, period; the fact that no one 
steps forward to maintain/improve a given piece of code is generally a 
pretty good indicator that it's not widely used.

This was not the case here.
