Would like some clarification on Class Markdown in https://ideas.intersystems.com/ideas/DPI-I-542

I am a first time Python Contest participant and am interested in potentially implementing the community idea found in https://ideas.intersystems.com/ideas/DPI-I-542 if it is something relevant to Python.

Would anyone be able to shed a bit of light on what the desired outcome of that idea being implemented is? There were a lot of upvotes on that idea but there wasn't very much information in it. Thanks!
