ISTM, the example shows the (undisputed) utility of regular bound methods. How does it show the need for methods bound weakly to the underlying object, where the underlying can be deleted while the bound method persists, alive but unusable?

It doesn't. I seem to have misinterpreted your "Weakmethods have some use (...)" sentence. Sorry for the noise.
