They know the implications of a single engine aircraft
What they know is that they don't want GA aircraft flying over their house, and someone saying that if an aircraft has an engine failure when holding offshore and that's unsafe for the occupants, the natural reaction is going to be: better he has that engine failure out there than over a built up area.
I've had direct experience of the general public's perception of GA aircraft ops, so I know what I'm talking about.
As I said, run your proposal past AOPA before you do untold damage to GA
And I'm not sure I got an answer to my question: what exactly did you say to WLM ATC on the air recently?
