A Shipyard is for buying/selling ships surely? Ship transport isn't anything to do with that so surely falls under a different requirement?
Are you suggesting we shouldn't be able to transfer ships to Hutton Orbital?
And your take on including distance from star to destination into any ETA calculation? eg: Should an ETA be the same to a station 10ls from star as 100,000ls?
Isn't it likely going to be shipyard = ship storage.
And if you're swapping into a new ship then your old ship needs storing.
Therefore shipyard.
I suppose they could sort a new gui thing aside of the shipyard but my impression they don't want this to require significant work if possible.
