After the discovery of Zeke's new power, it's likely Marley tried the same or various other methods with their Warriors to see if there's anything similar in their lines as well.

Now we don't know exactly when Zeke discovered this new ability of his, and whether RBAM were still on Marley or were already sent for the Paradis mission, but it's apparent his royal blood is the reason to it.

None of the other Warriors are of royal blood (as far we know), so I don't think they have a similar ability like that of Zeke's spinal fluid.
