Personally, I've long thought that Team TRQS were Ozpin's 'favourites' during their time at Beacon much like RWBY are now. He trusted them with certain missions that had to be kept off of the official books. Atter they graduated, they went their seperate ways, and Huntsmen and Huntresses tend to do. Taiyang had a short-lived relationship with Raven before she vanished (possibly on a deep-cover assignment to infiltrate the White Fang). As Ruby mentioned, Taiyang and Summer occasionally went on missions together, and Qrow seems to have become a school teacher in the fullness of time although that may have been after some time as an active Huntsmen.

However, I think that, like Qrow, the other three members of TRQS continued to occasionally do little side jobs for Ozpin, all entirely off the books and firmly in the "If you are captured or killed, The Council will disavow any knowledge of your team and its mission" territory. It is entirely possible, IMO, that the other three were present at Summer's death.
