Not at all, it means unidentified, not ulterior meanings and innuendos...Unidentified, nothing more...
I think what you may have meant to convey is since it is completely unidentifiable that it has the possibility of being just about anything that would fit that shape.
Actually I meant common place things like commercial aircraft, birds, bugs, clouds and balloons that some are calling UFOs. They are UFOs to some folks......but not all. Just remember the balloon man from AU.
