Me too. I have a brass plate between the knocker and the bell that
says "PLEASE USE THE BELL". They still don't. The bell can be heard
all over the house, even at the end of the garden. The knocker can't.

I'm still pondering adding a circuit to the knocker so that, if used,
a loud voice intones: "PLEASE USE THE BELL!!".

I like that idea!

So do I. But rationally, if you are going to fit a switch to the
knocker why not make it operate the bell? An additional voice
announcement is optional: "I told you to use the bell!".

Because I could do all that locally, which makes life easier.

The bell push is wired back to an Arduino (and more) on the floor above.
