Yes, ideas: 1. The Taken where already investigating the Vault of Glass as evidenced by the Paradox mission. Seems like that was a test run on how Bungie would implement a VoG Taken Raid. 2. The Cabal could be interested in Crota's End to learn more about their enemy. They may not know we killed Oryx and so are still investigating anything about The Hive/Taken. The Vex are also interested after Taken broke into the VoG. They're only purpose in the Raid is to create an alternate timeline where Crota still lives (like Praedyth in the VoG). This way the Vex can learn by watching us kill Crota over and over while fending off the ignorant Cabal who don't know Crota and Oryx already died in our timeline. The problem is Luke Smith said there would be no elemental primaries (VoG Year 1 rewards). I guess Zhalo doesn't count. Maybe he meant legendary elemental primaries. Anyhow, because of that they must change the rewards. I think these are neat ideas to make them relevant. I'm sure others can be better/more creative.
