I think you were in a very small minority if you worried about traffic
not painted on TCAS and not reported by ATC.

From my observation of flight test and line crews most do not even
consider the possibility there could be other traffic out there and
they certainly spend no time looking for it. (Before you line pilots
that are also glider pilots jump on me - I said most, not all).

On a recent test flight a TA in a head on situation received no
attention at all until it turned into an RA. That incident was in a
glider hot spot but was not glider traffic.
