Depends on many things, specially in one's sense of reasonable. Which is really a vague term to be left so lightly.
Is 10 million unreasonable to demand to a 5k transport?
Is 15 million? The whole cargo? 1/3 of the cargo?
What would you demand to an ore hauler? The full cargo is quite valuable, demand him to drop all the cargo would be good? the equivalente in money?
This hasn't changed with the new rules, but it sure makes an interesting question when a ship can blow up a transport in less than 30 seconds. I'm sure more reports will arrive soon.
EDIT:
How would it change removing the CD slots from cruisers?
