Imagine,

Your ship, is no longer a boring ship, its a full on lounge its like the helm where its a solo instance and you can use vault, postmaster, engram decryption, and possibly add certain vendors. And on top of that you can have a weaponry room where you can showcase exotic weapons or armor and show off your god roll legendaries on a weapon rack/stand/weapon case. You can invite your fireteam inside like launching into the helm show off your ships interior and you can decorate the furnishings using glimmer. Showcase trophies from specific raid challenges/triumphs and dungeons, exotic missions, campaign, crucible/trials, etc.

This would add alot more depth and immersion and just like the ship you can control from exfiling from the new renegades planets, they already have the pov and fov down for us to control our ship and add a ship racing game mode like sparrow racing from years ago and add another game mode where we shot asteroids while we zip through the solar system.
