If Nagato summons them, they'll be far away from the battlefield anyways, so how is that a solution?

In any case, again, how do you know that things can be summoned to and from Kamui dimensions? I've given you two examples of different versions of summoning jutsu being deemed unable to escape. Kakashi didn't try to reverse summon himself with his dogs (less chakra taxing than Kamui) and both Obito and Minato believed that if Obito teleported him away then Minato would lose.

It's not a different dimension. FTG is space time jutsu as well. Not a separate dimension. The barrier cuts of chakra contact but they are still physically in our dimension, whereas Kamui dimension is completely separate.
