Prior to this change airline set the function for getting hunks only once, which works as long as you don't use simlar plugins for different VCS at the same time. If that was the case, only one plugin would have won, depending on the first buffer handled by these plugins. And although the code for the other plugin was run every time, you would never see the actual line changes, since airline didn't even bother checking. Now these plugins can be used side-by-side in the same Vim instance, e.g. gitgutter for, well, git and signify for the rest.
