Comment (by wonderboymusic):

 @tfrommen the point isn't to commit everything into trunk at once, the
 point is to use less globals in WordPress. The ideal is no global
 variables, but there is no chance of that happening and maintaining BC. In
 the meantime, let us imagine what incremental changes we can make that
 look towards that future.

 DI is an idea, not a requirement. Using composition is incremental, not a
 final solution. If we decide to use a Service Locator, we now only need to
 update 5 properties, instead of 40 instances within the methods. We could
 make the decision to use DI, or not, I haven't decided if the extra args
 are a good idea or not, but I do think composition is an improvement.

 We are in Alpha, this is exactly when changes like this go into trunk.
