?! Yes it should be instant. It's a game. Instant is good! The game has been crying out for this since day 1.
Yes, it's a game, but there's a spectrum along the way from arcade/'casual'/convenient <----> realistic/simulation/'boring', and this is one step too far towards the left-hand side IMHO.
Think about this. If the transfer allows cargo to be moved with the ship as well, then you can pretty much invalidate CGs. Why worry about pirates when you can 'teleport' stuff long distance. Having instantaneous movement, and universal storage systems is a far cry from the original 'game' being discussed in the Kickstarter, where ships were to be registered to home ports and even multiple ownership of ships was debated.
Heck, why bother with hyperspace jumps at all? Is the logical next step is just fast travel everywhere? Which kinda removes the whole point of Elite?
Yah - I'm slightly overreacting at present. At least all of those people dismissing NMS as arcade don't have a leg to stand on now.
