The real safety risk here is;
a. And environment where the perceived enemy are the very ones unlikely to realise that such a thing exists.
b. The RPT pilots who come and go all week get very comfortable with the warm fuzzy feeling of extra safety from this unknown to the enemy MBZ/CAGRO/AFIS/AFIZ/Alphabet Soup airspace.
I dare say 99% of PPL/CPL folk who do not travel there daily would not even realise it exists. If asked off the top of my head about that aerodrome I would have believed it was a CTAF like every other one with RPT jets coming and going.
The safety folks around would say latent conditions for a pharque-up. but at least they will have a well buried rule that says who was at fault.
