Hope this is not too off topic, but I always disliked the fact that Dragon2 still has a trunk that is disposed off for landing. I think that an integrated trunk would not only safe money but would also result in a more buoyant craft that should theoretically already slow down higher in the atmosphere and thus would - to my understanding - put less stress on a TPS.
That would seriously complicate the spacecraft.
Remember, Dragon was developed when SpaceX "didn't really know what they were doing" (their quote) with regards to designing a spacecraft.
So they chose to go KISS (Keep It Simple Silly).
They had bid COTS for both pressurized AND unpressurized cargo. Unpressurized had to go outside the pressure vessel, which in itself was based on existing-and-proven outer mold lines (again: KISS).
That led to the trunk as we see today.
Crew Dragon (aka Dragon 2) is still adhering to the KISS principle. The trunk from Cargo Dragon is beautiful in its simplicity so it was kept unaltered. Prime focus for Crew Dragon is focused on its primary function: fly crew. You don't go wasting money on something that doesn't need changing.
