...but then again, it could surely happen.
Airmanship and SA goes hand in hand. No SA, outside controlled airspace and with more than one target on TCAS, sure I will follow it, but if only one target at FL360 in controlled airspace and visual (since 80 miles in the contrails) plus maybe SA from ATC communication, I will assume the responsibility and ensure positiv separation by creating line of sight to the other aircraft.
Or you could just pitch up or down a couple of degrees and say "TCAS RA" on the radio. Then a few seconds later, once the TCAS is happy, you say "clear of conflict, returning to flight level 360" and gently return to your assigned level. It's not hard.
