With the latest developer version of Matplotlib (f288977) I see a deprecation warning related to the examples.directory rcParams even when not accessing that key specifically. For example:

>>> import matplotlib
>>> {}.update(matplotlib.rcParams)
__main__:1: MatplotlibDeprecationWarning: 
examples.directory is deprecated; in the future, examples will be found relative to the 'datapath' directory.

I'm not intentionally accessing examples.directory. Is there any way to avoid having this warning appear unless that key is specifically accessed?
