I understood that part when writing my last response. The reason why
you get sabattier and other effects with these additives is, in part,
but in a large part, due to amplification due to developer. If you
incorporate perturbation before amplification, effects from the
perturbation get amplified on top of the "signal." But if you add
perturbation without (or after) amplification, its effect is limited.

I still think that the kind of effects you get with POP (without
developer) is quite different, and probably rather limited. But one
can certainly experiment... (How do you contact print on wet paper? Do
you make disposable diginegs?)
