My first thought was that the GA needed to hang onto the intact ships of all classes because they might need them for any number of purposes ... primarily for refugee exac ships.
After all, would it not be safe to assume, (dangerous word!) that in a pinch a Sollie SD could easily endure over 30,000+ refugees crammed inside for a short 4 week hyper hop?

I would be absolutely stunned if anyone's SDs could carry 30,000+ refugees for 4 days, let alone 4 weeks. It's not a question of physical space (though I don't think there's that much spare cubeage on an SD, what with armour and cofferdamming and magazine racks etc etc etc), it's a question of life support, specifically atmosphere and water recycling. If you're talking about putting 30,000 extra people on an SLN SD, even if you cut the crew by three-quarters from 6,000 to c. 1,500 by leaving all the combat systems unmanned and not embarking marines (and that's assuming you could cut 75% of the crew out that way), you're still talking about a 400% increase in the number of people on board. I doubt a warship has 400% spare life-support capacity - that's all mass and volume that could be used for weapons, sidewall generators, EW hardware, magazine space, armour etc.
