Yes, we don't want to stack anything more deeply than that.  It really
is just a means of ensuring that you can import a selected portion of
scikit-image without waiting too long, or without loading unnecessary
dependencies (e.g., importing the io module will also import gstreamer
if available).  Also, in the most severe case where one sub-module
can't import, you can at least continue working with the rest.
