<div>Okay. I would still refrain from calling these things by the class of the object consuming them. DMFormFunction() and DMFormIFunction() seem fine, since these have a meaning independent of TS (although the DM has to then encode a transient problem).</div>

We have to make that clear somehow and I think naming it after TS is helpful. Otherwise I'll eventually just have a bunch of names (function, residual, rhsfunction, objective, gradient, jacobian, ijacobian, hessian) and not know which ones go together.</div>
