Are we still required to provide traffic information? ICAO 4444 has removed the requirement to pass traffic. I found this from Eurocontrol.

PROVISION OF TRAFFIC INFORMATION
Until now, controllers were required to provide traffic information to the aircraft responding to the RA. This requirement has been removed as it is believed that at that point ATC traffic information provides little added value to the flight crew and might be distracting. Moreover, traffic information may be inadvertently inaccurate as the position and altitude information are delayed in surveillance processing. In some case controllers found issuing traffic information difficult due to the proximity or overlap of the aircraft labels and symbols on the screen. Also, traffic information and the visual acquisition of the intruder could prompt the pilots to stop responding to the RA. The amended paragraph 15.7.3.2 reads as follows:
“When a pilot reports an ACAS resolution advisory (RA), the controller shall not attempt to modify the aircraft flight path until the pilot reports “Clear of Conflict”.
