I don't know about you, but I don't want to have a bad experience trying to find space for my newly collected items on the last content release before D2.

Alot of people collect valuable weapons as trophies, memories of what they've done. However if they were to have every one it would be over 156 weapons, leaving no space for others or infusion fuel. That's just weapons though, I don't want to even start on armor.

I wouldn't say that you necessarily need to keep them. They did say, however, you'd still be able to keep all of this stuff in your vault for Destiny while you play Destiny 2. I mean, why do you collect anything in any game? I collect dog tags and such in the Battlefield games knowing full well that they won't follow over into the next BF game. But, I still enjoy the grind for each one.
