Buckshot. No not news. It's well known. Look up atsb report 199601917 re a serious breakdown of separation between a 747 and a BA146 On 21 June 1996.
OK, so it was only one incident, 20 years ago, not many more as you inferred
and there were other more serious causal factors than communicating with a VFR aircraft who was being provided with a RAS.
Given the ATC vertical resectorisation since then, the likelihood has been reduced.
