Problem

Compare with:

This holds for more of the newly deprecated modules, including docstrings. tight_bbox, tight_layout, and type1font.

Suggested improvement

Not sure what the right thing to do is, but I do not think that this should be empty (hence Release critical in some sense).

Ideally there should be a deprecation notice for the module and the "old" information?
