The worst that will happen is that it might irritate airlines or ATC
Many GA and RAA pilots make the following calls:
10 miles
5 miles
Joining circuit
Joining downwind
Joining base
Joining final
Vacating the runway
Let's take the case of a flyaway for a BBQ ... to a strip not marked on any charts and the above dudes are out in force. It is also a busy Sunday for the good folk at Flight Service, a lot is happening, many area frequencies are tied together, staff are few.
I see mega irritation happening!
