Didn't stop them with the Starfarer, as you say the Reclaimer, the Relent SEN, Reliant Mako, any Origin ship as the Luxury gameplay isn't in yet, any explorer ship like the Carrack.... actually almost any ship with a focus which isn't combat or Cargo :)
But yes I see what you mean I think the current thinking is should they push this limited use liner to completion or a bunch of smaller craft which more people have access too. I see value in both, personally I have my favourite ship/s flyable so I'm cool with the BMM being completed at the cost of waiting a bit longer for the X1, G12, 600i rework etc - Get the big job out of the way and the little jobs will be done quick after that. Do the little jobs first... and there will always be more little jobs that come along and get in the way of getting back to the big job!
