Is there anything blocking this PR?

The main consideration is that empty_graph is used extensively (both within the library and user code), so this change has the potential to introduce subtle bugs that aren't caught by the test suite. NetworkX 3.0 is slated to come out in the very near future, so this PR is waiting until after that release in the interest of risk-avoidance.
