So we as a community have expressed out desire outright and consistently about bringing back old content. Personally I love VoG, and having to go through it to obtain a part for No Time to Explain was one of the most fun times I've had since you launched TTK. I am in no way saying TTK is bad, I love the game as a whole.
Now for my suggestion. So what if instead of the progression team feeling as if the are required to bring back old gear (obviously I don't know the real issues but that's my speculation) the raids were updated via level and all Bosses and checkpoints offered a redeemable item to buy a piece of loot from either a vendor or a new set. Like how PoE dropped weapon and armor cores. This would offer us ample reason to run our old/favorite content.
Anyway, that's my piece. Can't wait for the April update, it seems you guys have listened to our concerns about time input so thanks!
