I suppose if my starship so happened to be the first to arrive, I would enjoy having an easy impulse burst straight to the doors. Though to be fair consider how many starships spawn at that point of arrival? Sometimes 10+ starships can be seen just sitting out there. My ship arrives late to that particular party and is spawned above, below or to either side of the fleet.
It really depends upon how patient I am to get into Spacedock that day. Sometimes it's a challenge to gracefully maneuver my starship for that perfect alignment to the space doors. This is likely why manual docking is optional. not everyone takes the time to reach those doors at all.
Now if we do get lucky later, we might get a cutscene from the interior of Spacedock. This might be the only way to counter the fact that Spacedock is, technically, a shared experience. By default, a cutscene would perfectly center our unique starship model as it crosses the threshold.
