Reckoner too now will be gone completely, given that Gambit Prime armor and Reckoning will no longer exist in Beyond Light. The one question mark title is Wayfarer, which requires at least some things from Vaulted Zones, but it's possible those requirements could be removed.

Is the reckoner title going away?

The Reckoner title first arrived during Season of Drifter in 2019, and involves playing more games of Gambit Prime than I ever wanted to play. But Reckoner is leaving the game on Nov. 10.

Which titles are getting vaulted?

With the vaulting of Io, Titan, Mars, and Mercury there's a bunch of content leaving Destiny 2 for the foreseeable future.
